Action is the real measure of intelligence.
You’ve got to be sure of yourself before You can ever win a prize.
Hard labor and good intentions are not sufficient to carry a man through to success.
Somewhere in your make-up there lies sleeping, the seed of achievement which, if aroused and put into action, would carry you to heights, such as you may never have hoped to attain.
Enthusiasm is the steam that drives the engine.
People who do not succeed have one distinguishing trait in common. They know all the reasons for failure, and have what they believe to be air-tight alibis to explain away their own lack of achievement.
