The difference between great and average is how often you take risks.
Accept risk as a normal part of living. View risk as a part of the process of exploring your world. Make note of the lessons you learn with each chance you take and move on.
Forget about the consequences of taking chances. Risk opens you to only a temporary change in direction that can set you straight for your next success.
If you're brave enough to risk, to temporarily live outside of your comfort zone, for a short period of time, you're big enough to win.
