It's ok being wrong as that is very much part of the 'game'.
The truth is that trying hard to be right would be a waste of energy and time. The best one can do is to try to increase one's chances of profits as many times as possible on a percentage basis. Losing is part of the 'game'. Bernard Baruch said "Don't try to buy at the bottom and sell at the top. It can't be done except by liars.", and "I made my money by selling too soon." GLTY
