I agree that the biggest enemy to me is myself.
if I can overcome my rapacity, I might not be sad as I am right now, losing too much and want to take back money from market, don't want to accept that lost.
there is no learning without failure at the beginning even Einstein failed also early in the experiment
and How to fight with yourself ? my advice, try to have a friend who is better than us I am sure that if we live in an environment and a successful friend it is better if we just try ourselves without seeing a real example
