What about people that actually feel the contrary state of mind?
I sincerely think trading has made me a more stable, balanced person than before... I wasn't made for the brutal change between physically and cerebraly motivational youth/school to boring relation-based model of corporate work.
First, trading gave me a challenge( be profitable ) and then a way to live, enjoy life and make projects, and it still requires some brain work, more than in most jobs( I'm totally down to re-begin from scratch if my methods don't function anymore).
I don't know if my brain was originally damaged but I really enjoy this video game kind of lifestyle, I feel that I was quite made for it( at my little level ) and moreover, talking to profitable traders, feeling brain damaged, depressive... without any objective reason is quite overrated nowadays...
