TL;DR:

ADHD pops up in times and places of crisis. People with ADHD handle crises well and are mentally built to survive them. They can hyperfocus on one thing and have an easier time seeing the big picture of a situation. They tend to have trouble in peacetime. They experience stronger emotions and tend to act on impulse. Stimulant meds allow them to better use the executive portions of their brains. They should try to find jobs that play to their strengths, either hyperfocus or responding to crises.
