I resemble that remark :)

Kidding aside, there are many *very* succesful "non-linear" thinkers
who have learned to deal with their own situations. Key phrase being
"learned to deal with". I can imagine that someone w/ADD who is forced
into a normal "linear thinking" job or profession might be very edgy
or unhappy/unproductive.

I happened to find a profession where I excel because of my traits.
Another individual I know who is *more* ADD that I found his calling
as a househusband/coach. I all depends on how far you are willing to
go to find that which suits you best.
