Acceptance of the fact that I will always have executive function difficulties and there is nothing that can really improve it. It's not the realization I wanted to have, but it is one I wish I learned earlier.

Accountability, mostly. Either by gamification, for example a simple small whiteboard counting how often I did y (or not, that would be a strike). Couple with someone holding me accountable it works wonders, throw in a "punishment" or reward... Or, if that doesn't fit, deadlines (which maybe is just another kind of accountability...). Both made me finish my degree in time and with a very good grade (A in Americano?).

How to translate this into the workplace, I'm not sure. You might have a supportive workplace and can be open about it, which is what I did.
