The Weasel’s Energy Budget: How I Decide What's Worth Spending Energy On

Written by J.T. Oden

Most of us have a budget.

We know how much money we have, how much we can spend, and what happens when we overspend.

For most of my life, I've lived with another kind of budget.

Sickle cell disease taught me early that energy is a finite resource. Long before my stroke, I was already making calculations that many people never have to think about. How much can I take on today? How much recovery time will I need afterward? Is this worth the risk of overextending myself?

For years, those calculations became second nature. They weren't always easy, but they were familiar.

Then I had a stroke that temporarily paralyzed my left side.

The energy budget I had spent years learning to manage had now become more complicated.

The stroke didn't introduce the concept of limits. It changed the nature of them.

Those of us living with chronic illness often have a second budget running quietly in the background at all times: an energy budget.

Unlike money, this budget is invisible. No app tracks it. No bank statement summarizes it at the end of the month. Yet nearly every decision we make is influenced by it.

And unlike money, we can't simply borrow more when we run out.

We can ignore the budget. We can pretend the balance is higher than it is. We can spend beyond our limits.

But eventually the bill comes due.

Over time, I've learned that managing energy is not just about avoiding exhaustion. It's about deciding where that energy will have the greatest impact. And the longer I live with chronic illness, the more I realize that this budget influences far more of life than most people ever see.

Every Day Starts with a Different Balance

One of the hardest adjustments after my stroke was accepting that wanting to do something and being able to afford it are not always the same thing.

There have been times when I looked at my calendar and saw plans I genuinely wanted to keep. Nothing about them seemed unreasonable. A gathering with friends. A project I was excited about. A commitment I had made with every intention of following through.

Yet as the day approached, it became clear that keeping that commitment would require energy I no longer had available.

Those moments are frustrating because the desire never disappeared. The interest never disappeared. The intention never disappeared.

Only the available resources changed.

From the outside, cancelling a plan can look like a choice.

From the inside, it can feel more like accepting a reality that was never part of the original plan.

Some mornings I wake up feeling relatively capable. Other mornings I feel as though I've already spent half my energy before my feet hit the floor.

The frustrating part is that there isn't always a clear reason why.

Maybe I slept poorly. Maybe my stroke damage is affecting my cognition more than usual. Maybe my body has simply decided that today will be more painful than yesterday.

Whatever the reason, I begin each day by taking stock of what I have in the bank.

The challenge is that this bank account isn't predictable. Unlike a paycheck that arrives on schedule, my energy reserves can fluctuate from one day to the next without warning. A day that looked manageable on the calendar can suddenly become a day where even basic tasks feel expensive.

What makes this especially difficult is that there is rarely any advance notice. I don't get an alert telling me that today will be a low-energy day. I discover it in small ways: how heavy it feels to get out of bed, how long it takes to organize my thoughts, how much effort it takes to start tasks that seemed simple the day before.

That uncertainty changes the way I approach everything. Most people can make plans assuming that tomorrow will be roughly similar to today. I can't always make that assumption. A commitment that feels reasonable when I schedule it may feel overwhelming when the day arrives. The calculation is constantly changing, and so I have learned to leave room for adjustments.

Over time, I've realized that managing my energy isn't just about dealing with fatigue or pain. It's about navigating unpredictability. The physical limitations are challenging enough, but the inability to know exactly what resources I'll have available on any given day adds another layer of complexity.

Each morning becomes less about what I want to accomplish and more about understanding what is realistically possible. Before I can decide how to spend my energy, I first have to determine how much of it I even have.

The Cost of Ordinary Things

One of the strangest parts of my post-stroke life has been realizing just how much everything carries an inflated energy cost.

Showering costs more energy.

Cooking costs more energy.

Driving costs more energy.

Answering messages costs more energy.

Even activities I enjoy now come with a larger price tag than they once did.

Reading a book.

Working on a hobby.

Going out with friends.

Writing this article.

The question isn't whether something costs energy.

The question is whether the return is worth the investment.

What took me a long time to understand is that the cost isn't always visible. Sometimes I can point to a reason. Poor sleep. Increased pain. A particularly demanding day. But other times the expense comes from something harder to explain.

Before my stroke, much of life operated on autopilot. My brain quietly handled countless small tasks in the background. Following a conversation, filtering distractions, organizing thoughts, remembering what I was doing, shifting attention from one thing to another—these processes happened automatically. They required effort, but it was effort I rarely noticed.

Now I notice it.

Activities that once felt simple often require a level of conscious attention that they never did before. A crowded room demands more mental filtering. A change in plans requires more adjustment. A conversation with multiple people can feel like trying to keep several spinning plates balanced at once.

From the outside, nothing appears unusual. I'm sitting in a chair. Driving a car. Reading a page. Talking with friends.

Internally, however, there is often far more work happening than there used to be.

That invisible mental tax accumulates throughout the day. Each decision, interruption, distraction, or unexpected problem withdraws a little more from the account. Individually, none of these withdrawals seem significant. Together, they can leave me wondering why I feel exhausted despite having done nothing that appears particularly demanding.

One of the lasting lessons of stroke recovery has been learning that energy isn't spent only through physical exertion. Sometimes it is spent through concentration. Through adaptation. Through the extra mental effort required to navigate a world that once felt automatic.

The activities may look the same as they did before.

The cost of performing them does not.

Energy Return on Investment

I've spent most of my life thinking about energy.

Long before my stroke, sickle cell disease taught me that energy was not an unlimited resource. I was already familiar with tradeoffs. I already knew that pushing too hard today could create problems tomorrow. I already understood that some days required more caution than others.

The stroke didn't introduce the concept of limits.

It changed the nature of them.

Now there are costs that are harder to see. Physical exertion is only part of the equation. Concentration has a cost. Decision-making has a cost. Navigating distractions has a cost. Adapting when something doesn't go according to plan has a cost.

As a result, I've become more selective about where I invest my energy.

Not because every activity must be productive, but because every activity asks something of me.

A conversation with a friend may leave me tired, but it also leaves me feeling connected.

Working on a project may require significant mental effort, but it gives me a sense of purpose.

Writing may drain my focus for hours, but it helps me understand my own experiences and share them with others.

Those investments cost something, but they also give something back.

What I've become more aware of are the activities that consume energy without providing much return. The errands that require constant course corrections. The administrative tasks that generate more frustration than progress. The situations that leave me mentally exhausted yet wondering what I actually accomplished.

The challenge is that the energy cost is often invisible.

Two hours can look identical on a calendar while feeling completely different in practice. One activity may leave me tired but satisfied. Another may leave me equally tired with little to show for it.

That's why I think about energy and time differently.

Both are limited resources. Both matter.

But time measures how long something takes.

Energy determines whether I can fully participate in it.

And when energy becomes the limiting factor, the value of what I receive in return becomes impossible to ignore.

The Hardest Part: Saying No

Sickle cell disease has thoroughly taught me that limits are real.

From a young age I already knew that not every invitation could be accepted. I already knew that rest was sometimes necessary. I already knew that pushing through exhaustion could create problems that lasted far longer than the activity that caused them.

What the stroke changed was not the need for boundaries.

It changed where those boundaries exist.

Activities that once felt manageable now require more planning. Tasks that used to have a predictable cost can now vary dramatically from one day to the next. The margin for error has become smaller.

As a result, I find myself saying no more often than I would like.

Not because the opportunities aren't worthwhile.

Not because the people aren't important.

Because every commitment draws from the same limited pool of resources.

The difficult part is that many of the things I decline are things I genuinely want to do.

I want to show up.

I want to help.

I want to participate.

I want to say yes.

That is what makes these decisions difficult. There is often a real sense of loss attached to them.

But experience has taught me that energy spent in one place is energy unavailable somewhere else.

Sometimes saying yes to an extra commitment means having less to give my family later.

Sometimes pushing through fatigue today means paying for it over the next several days.

Sometimes the choice is not between doing something and doing nothing. It's choosing which responsibility, relationship, or priority needs my energy the most.

I've learned to think less about what I want to do in a given moment and more about where I am most needed.

That doesn't eliminate the disappointment. There are still opportunities missed, invitations declined, and plans postponed.

But I've come to understand that saying no is not always a rejection.

Sometimes it is an act of stewardship.

Sometimes it is the decision to preserve enough energy to be present for the people and responsibilities that matter most.

And sometimes the most responsible choice I can make is accepting that I cannot do everything, even when I wish I could.

Prioritizing What Matters

One of the lessons I've learned from living with sickle cell and recovering from a stroke is that limitations reveal priorities.

Because they make priorities unavoidable.

When energy is plentiful, it's more plausible to give attention to almost everything. Responsibilities, relationships, projects, obligations, hobbies, and distractions can all coexist without forcing many difficult decisions.

Limitation changes that.

It forces questions that are easy to avoid when resources are abundant.

What absolutely needs my attention?

Who depends on me?

What responsibilities cannot be neglected?

What brings meaning to my life?

Those questions don't always have comfortable answers.

Sometimes the responsible choice is spending energy on work when I would rather spend it elsewhere.

Sometimes the right choice is prioritizing recovery even when it feels unproductive.

Sometimes family needs my attention more than personal goals.

Sometimes the opposite is true.

The challenge is that all of these things matter.

The lesson has not been learning how to identify what is important.

The lesson has been accepting that important things still compete with one another.

Over time, I've stopped measuring success solely by how much I accomplished in a day.

Instead, I try to evaluate whether I spent my energy in alignment with the things I value most.

I don't always get it right.

But limited energy has taught me that a meaningful day and a productive day are not always the same thing.

And understanding the difference has become one of the most valuable skills I've developed.

What I've Learned

If there's one lesson this budgeting process has taught me, it's that energy is valuable precisely because it's limited.

When I had more of it, I spent it without much thought.

Now I spend it carefully.

Not perfectly.

Not always wisely.

But consciously.

And while I would never choose the challenges that my ailments bring, there is something strangely clarifying about being forced to evaluate what truly deserves my time, attention, and effort.

Every day, whether I realize it or not, I'm making investments.

The goal isn't to spend energy on everything.

The goal is to spend it on the things that matter most.

Final Thoughts

Most people never have to think about energy this way.

They wake up assuming that the resources available today will probably be available tomorrow. They make plans without wondering whether their body or mind will quietly change the terms of the agreement overnight.

Chronic illness doesn't always allow that assumption.

It forces awareness.

It forces adaptation.

It forces intentionality.

I would never choose sickle cell disease. I would never choose a stroke. I would never choose the challenges either has brought into my life.

But both have taught me something I might not have learned otherwise.

Energy is not valuable because it is abundant.

It is valuable because it is finite.

And when something is finite, every investment becomes meaningful.

Every yes.

Every no.

Every commitment.

Every moment of rest.

Every decision about where to spend the resources available today.

The budget may be invisible.

But its influence is everywhere.
