There must be a difference between these two groups of traders – the small minority of winners and the vast majority of losers who want to know what the winners know. The difference is that the traders who can make money consistently on a weekly, monthly, and yearly basis approach trading from the perspective of a mental discipline. When asked for their secrets of success, they categorically state that they didnt achieve any measure of consistency in accumulating wealth from trading until they learned self-discipline, emotional control, and the ability to change their minds to flow with the markets.

You can give anyone the best tools in the world and if they don’t use them with good money management, they will not make money in the markets…. 
Fear: fearful of profit and one acts too soon.
