Are professional athletics handicapped by their state of mind especially when it comes to baseball?

Question

Baseball is known to be a game of failure. Professional baseball players seem to have a better grip on handling failure because they forget about the previous game and move on to the next game after they lost. Why do some pro-athletics not worry about their mechanics while others do? Maybe sometimes it is better to just trust in their own abilities instead of overthinking the situation.

Answer 1

They are conditioned by the amount of games played and hitting. In batting 3 out of ten is good. Anyone playing baseball is conditioned since childhood.
