Flaming enthusiasm, backed by horse sense and persistence, is the quality that most frequently makes for success.
Success is the ability to go from failure to failure without losing your enthusiasm.
Sir Winston Churchill
I don't measure a man's success by how high he climbs but how high he bounces when he hits bottom.
General George S. Patton
I don't know the key to success, but the key to failure is trying to please everybody.
It is wise to keep in mind that neither success nor failure is ever final.
Eighty percent of success is showing up.
