Failures are finger posts on the road to achievement.
C. S. Lewis
Defeat is not the worst of failures. Not to have tried is the true failure.
George Edward Woodberry
Happiness is not something ready made. It comes from your own actions.
A failure is not always a mistake, it may simply be the best one can do under the circumstances. The real mistake is to stop trying.
B. F. Skinner
Ambition is the path to success, persistence is the vehicle you arrive in.
William Eardley IV
