If you have ever done a P90X workout, you probably remember Tony Horton saying “Do your best and forget the rest.” It is one of his mantras intended to empower and get everyone to try each activity. You will never know all that you can achieve without making an attempt. If you continue to do your best over a period of time, your best should improve. This is also a helpful mantra for those who get caught up in perfectionism and competition. It is a reminder to stay focused on the task at hand, which will lead you to your goal, and ignore all the other variables and distractions.
Perhaps a personal example will make things more clear. Reh
