Quote from achilles28:
Have you considered an inverse relationship?
Success causes elevated testosterone.
Several animal and human studies prove such a relationship.
Success with mates or 'dominating' pack members creates such boosted effects.
The gyms always a good bet, though.
Absolutely this is so, also a major handicap to pushing yourself trading from home is the absence of male group dynamics. I most other businesses either you knew who the competition wa s and where you stood in relation to them or there was an alpha male (top sales guy etc) whose crown was your target. One of the problems with trading generally/trading from home is there is no readily identifiable competitor to go after.
