My DD's first TB HC had a great saying..."control what you can control" and "what was the least important pitch - the last one, what is the most important pitch - the next one"!
I recall DD's first rec ball coach (he is a TB coach now...I think 12U?) saying "What is the least important play? The last one. What is the most important play? The next one!" He is reason DD is still playing softball today.
