"...it has also been my observation that a majority of all entrepreneurs have Attention Deficit Hyperactivity Disorder, or AD/HD."

Actually in my case, my start-up actually took me OFF my ADD-type symptoms. I realized that I had too many ideas that were keeping me from actually working on ANYTHING including school work. Soon as I settled on ONE startup idea, I could quit thinking about potential ideas and started work on that ONE idea.

After starting work on the startup, all of a sudden I was short of time and naturally forced to plan my day better.

adhd and add are overrated. so many people have it. i was even diagnosed with it. its just so easy to fit into the DSM/IV description. http://en.wikipedia.org/wiki/DSM_IV

Haven't read it yet, but my first impression strongly agrees with the premise of the article.
