Keep trying. Stay humble, Trust your instincts. Most importantly, act. When you come to a fork in the road, take it.
Somethings don't always work out the way you plan. The main thing is to keep trying, do better next time, and deal with disappointment if it comes.
Buy a stock, if it goes up, sell it, if it goes down, don't buy it.
Whatever you do, you should do it with feeling.
How can you think and hit at the same time?
As a general comment on baseball:"90% of the game is half mental."
