There was a stretch early in my consulting career where I would come home most evenings and struggle to decide what to eat, not because I didn’t know what I wanted, but because I had nothing left to decide with. I didn’t have a name for it then. Now I recognize it immediately: decision fatigue, and for ADHD and autistic brains, it tends to arrive faster and hit harder than most productivity advice accounts for.
Every decision, regardless of size, draws on the same limited mental resource. What to work on first, how to word a message, whether to accept a meeting time, what to prioritize when three things feel urgent at once. None of these individually feel like much. Added together across a normal workday, they add up to a significant drain, and by the time an important, high-stakes decision actually needs to be made, the resource available for it is often already thin.
This matters enormously in business, where the decisions that actually move things forward, pricing, hiring, strategy, tend to arrive at unpredictable times, often stacked on top of a day already full of smaller ones. I noticed that my worst business decisions, the ones I regretted later, almost always happened late in the day, after a long string of minor choices had already used up most of my decision-making capacity.
The system that fixed this for me was ruthlessly reducing the number of low-value decisions I make in a day. Recurring choices got turned into standing rules instead of live decisions: fixed pricing structures instead of negotiating from scratch each time, template responses for common client questions, a fixed weekly schedule instead of deciding each morning what to work on. None of these individually seem important, but removing dozens of them daily left noticeably more capacity for the decisions that actually mattered.
I also started scheduling important decisions deliberately, the same way I’d schedule an important meeting. Big strategic choices happen early in the day or early in the week, before decision fatigue has had a chance to accumulate. Anything that arrives later and isn’t genuinely urgent gets deferred to the next available high-capacity slot rather than decided immediately under fatigue, even when there’s social pressure to answer right away.
Delegation became part of this system too, not just as a way to save time, but specifically as a way to protect decision-making capacity. Every decision I hand to someone else, even a small one, is one less draw on a resource that runs out faster than most advice assumes. I stopped viewing delegation purely through the lens of time saved and started viewing it through the lens of decisions preserved for the things only I can decide.
If you find your judgment getting worse as the day goes on, that’s not a discipline failure. It’s a resource being spent, the same as physical energy. Reduce the number of small decisions you make by turning repeatable choices into fixed rules, protect your best decision-making hours for what actually matters, and treat delegation as a way of budgeting judgment, not just time.
