Shake off your blunders. How will you know your limits without an occasional failure? Never quit. Your turn will come.
Failure is... the highway to success.
Cultivate the habit of laughter.
Tomorrow is only found in the calendar of fools.
Act now, for now is all you have.
The weakest living creature, by concentrating his powers on a single object, can accomplish good results while the strongest, by dispersing his effort over many chores, may fail to accomplish anything.
