"Practice makes perfect" is a very wise saying. Practice builds confidence, as well. The visiting team cannot wait to go practice on the opposing team's home field before game time. Visiting teams are not familiar with the turf, and they will also face hostile sports fans. Even professionals have to "get the bugs out." If you do not have a stage or a field to practice on, you still have your mind. In Yogic meditation, you are taught to visualize. Therefore, you should visualize success. Do not approach a negative thought as a victim. Instead, look at your problems as a victor would. Forget the worries and focus on the solutions. Some of my Yoga students have said, "But what if I fail?" In truth, no adventure in this life is a failure, unless you quit. If you never give up, you are still working on a positive outcome.
