For the other hand, at home and wandering around on weekends, I had a blast.
At school I mostly felt dead; when I was allowed to do what I wanted, I felt alive. I felt in public school I was just a cog in a Machine.
And there was no ADHD was I was a kid. None. One reason, I think, is that after school and on weekends our parents kicked us outside to play. I'm only half-joking there, because they didn't have to kick us outside.
I also found that when we collaborated on things it was a lot more fun. Sometimes, of course, I preferred to work on things myself. But hanging with my smart friends - we got things done.
Turns out that collaboration - two heads is better than one - is what created every "Enlightenment" that ever existed.
Sir Ken Robinson says it better.
