“No matter the task at hand, there is always opportunity for self-doubt.  Whenever you decide to follow a dream or set a goal, you are just as likely to come up with all the reasons why the likelihood of success is low.  Blame it on the f*cked-up evolutionary wiring of the human mind.  But you don’t have to let your doubt into the cockpit!  You can tolerate doubt as a backseat driver, but if you put doubt in the pilot’s seat, defeat is guaranteed.” ~ David Goggins, Can’t Hurt Me
