But you dont have to let your doubt into the cockpit! You can tolerate doubt as a backseat driver, but if you put doubt in the pilots seat, defeat is guaranteed.

It will allow you to control and manage doubt, and keep you focused on taking each and every step necessary to achieve the task at hand.
