I can do it. That doesn’t mean I can do it again. And it feels like an obstacle course.
So here’s something I struggle with: explaining to people that being able to do something tells you very little – almost nothing, in fact – about what it costs me.
I can attend the appointment. Have the conversation. Follow the instructions. Sometimes I can do all of those things quite well.
And then that’s it. That’s the day.
From the outside, the evidence is that I did it. From inside, there’s considerably more information. You guys get it. What came before? How much did I have left when I started? What did I have to give up afterward? Could I do it tomorrow?
I’ve been thinking about this as the difference between capability and capacity. And to me at least that distinction is useful.
Capability: I can do the thing.
Capacity: how long, how often, under what conditions, and at what cost.
My half-hour vision rehab appointments use up the rest of my day. The appointment was only thirty minutes. My brain apparently hadn’t agreed to that schedule.
It can feel like an obstacle course where each station looks manageable on its own. I actually see the obstacle course in my mind’s eye. Stairs, a balance beam, instructions to follow, a passage to read and remember. But the balance beam is different after the stairs. Remembering the passage is different after everything that came before it.
And finishing the course doesn’t tell you whether you can make dinner. It tells you nothing.
This is the part I wish more people understood. Including, sometimes, me. I can still catch myself using something I managed yesterday as evidence of what I should be able to do today.
But yesterday’s result was yesterday’s result. It didn’t come with a guarantee.
Any of this familiar? Does the capacity vs. capability distinction make sense? What’s something you’re capable of doing that costs more capacity than anyone sees?
