Procrastination is the fear of success. People procrastinate because they are afraid of the success that they know will result if they move ahead now. Because success is heavy, carries a responsibility with it, it is much easier to procrastinate and live on the 'someday I'll' philosophy.
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.
