135: ADHD & Your Home – How to Get Yourself to Do What You Know Needs To Be Done

It’s Never Been a Knowledge Problem

I recently came across a clip of a 2012 speech by Dr. Russell Barkley that put words to something I’ve been trying to say on this podcast from the very beginning. In it, he describes ADHD as a split between knowing and doing. You can be the brightest person in the world, and it won’t matter, because you can know exactly what to do and still not do it. He calls it a performance disorder, not a knowledge disorder, a disorder of the when and the where, not the what and the how. The problem was never not knowing what to do. The problem is doing what you already know.

Why this matters so much to me

This is the entire reason I started this podcast. I used to sit in professional organizing circles listening to well-intentioned colleagues talk about their ADHD clients as though the issue was simply a lack of instruction, that nobody had ever taught them how to clean up, put things away, or set up a system. So the proposed fix was always the same: teach the right system, teach the right routine, get the space organized once, and then just maintain it. That’s not the answer, and it never was. If you’ve ever felt like you’re “having trouble with maintenance,” that’s not a separate problem to solve, it’s the exact same knowing-versus-doing gap that got you there in the first place.

What actually helps

Two things make a real difference. First, genuinely having less stuff to manage, decluttering isn’t just a nice bonus, it measurably changes how manageable everything else becomes. Second, having things organized so they truly have a home. But beyond that, the real shift comes from externalizing your systems, your sense of time, your follow-through, your accountability, rather than relying on internal willpower or memory to carry it. That means accepting that our brains function differently, not worse, just differently, and getting creative about how we exercise action instead of assuming we should be able to just remember and follow through the way a neurotypical brain does.

Progress is genuinely possible

None of this is a life sentence. Understanding that the barrier is executive function, not intelligence or effort, and building external supports around that reality, whether that’s an accountability partner, a group, or simply a system you don’t have to hold entirely in your head, is what actually creates room for change.

Your practical, actionable step

The next time you catch yourself thinking “I just need to learn the right system” or “I know what to do, I just can’t seem to do it,” recognize that as the performance gap, not a knowledge gap. Instead of searching for more information, look for one way to externalize the task, a timer, a friend to check in with, a visible reminder, anything that moves the follow-through outside your own head.

Until next time, continue to choose joy.
