Everything I learned in school about taking notes and daily planning was nearly useless to me. I had to re-learn this skills later in life, because the old way of "this is how it's done, period" did me no favors.

For that last bit, I'm pretty good about breaking bigger projects down into smaller pieces. After "paint the living room" lands in my inbox, I'll decompose that into things like "look for nice paint colors", and "ask my wife what kind of curtains she likes". Each of those is easy to do for that quick dopamine hit.
