For me, it was accepting that I will never be the smartest guy in the room and never know the most about a topic. I decided to play to the strengths that come from ADHD, and have cultivated broad knowledge, with only a few points of depth. I work with AI/ML, and I transitioned into it from web dev. I make a point to learn what I need when I need it, rather than trying to stuff my head full of stuff that may or may not be relevant. Changed my focus to "be good in the current situation" rather than "be good at everything." Over time, that fosters learning that sticks.
