I've read that a disproportionate number of people who work for themselves are dyslexic or have ADHD. My hypothesis is that these people are driven from companies unfairly when they cannot “prove themselves” in entry-level jobs where inability to do close detail work gets them labeled as lazy and sloppy.

I once worked with a person who said she got straight As in a PhD program, then transferred to law and was nearly failing. She got tested by a learning specialist: result, 160 IQ and ADHD. Yet in our workplace people labeled her “stupid” because she could not keep up with tasks that required extreme concentration.
