To succeed in the world it is not enough to be stupid - one must also be polite.
If at first you don't succeed, try, try again. Then quit. No use being a damn fool about it.
Success is getting what you want, happiness is wanting what you get
If you’re in the luckiest one per cent of humanity, you owe it to the rest of humanity to think about the other 99 per cent.
Success is stumbling from failure to failure with no loss of enthusiasm.
Winston S. Churchill
Success is not final, failure is not fatal: it is the courage to continue that counts.
