[Those with attention deficit hyperactivity disorder (ADHD)]...get hyperfocused on a problem that captures their attention, especially when the tasks they “should” be working on seem boring or impossible to a less-than organized mind. When that hyperfocus leads them to some measure of success, they are told that their achievements are not welcome. So they set out on their own. Not so much because they intended to be entrepreneurs, but because their consistent habit of acting without thinking nudges them onto their own path.
