Each at-bat is a new day.
We don’t just have the opportunity to start fresh each day. We have the opportunity to start fresh each moment.
We can learn from past failures and mistakes, but we shouldn’t get stuck there. We can keep future goals in mind, but we shouldn’t get stuck there, either. The only way to reach our potential is to focus on what we must do now – this moment, the day – to perform effectively and to win.
In baseball, a hitter mired in a slump can belt a home run on any pitch. A team on a prolonged losing streak can always win that day’s game.
