How to be a winner from right this moment?

A real winner is OK even when they lose. They get right back up and try again. Even in loss they win. You sound like one of those. If you are young you will probably have many wins and losses in your lifetime. A guy like Edison made thousands of mistakes before he was able to come up with the right elements to make a light bulb. Each failure was a stimulant to the next failure until finally he did it right. Imagine that.
