Peak performance occurs when you perform to the peak of your ability. In order to do this you need to be clear on what you want to achieve and what is important to you. You need to focus on your life and your priorities.
Peak performance allows you to live the best life you can. Performing at your peak creates benefits for everyone that you come in contact with, not just yourself.
If you want to achieve peak performance, you need to be able to maintain your focus on the small number of important activities which will enable you to create the life you desire. Peak performance is a life commitment. You will always be able to find new ways to improve your performance if you are willing to look for them.
