Better get a stiff neck from aiming too high than a hunch from aiming too low. Failure should be our teacher, not our undertaker. Failure is delay, not defeat. It is a temporary detour, not a dead end. Failure is something we can avoid only by saying nothing, doing nothing, and being nothing. One cannot govern with buts. You cannot pick cherries with your back to the tree. You do not have to be a fantastic hero to do certain things, to compete. You can be just an ordinary chap, sufficiently motivated to reach challenging goals.
