What task do you keep doing yourself instead of teaching someone else?

I noticed something about myself last week. There is a task I redo every single time instead of handing it off, not because nobody could learn it, but because writing down the steps felt heavier than just doing it again myself. That quiet decision, made over and over, is probably costing me more than the task itself ever could. I am curious whether other founders have the same one thing, the task everyone assumes is delegated by now, that is still quietly sitting on your own desk because teaching it once felt like too much friction on an already full day. What is yours, and what has kept you from finally writing it down?
