If you believe in what you are doing, then let nothing hold you up in your work. Much of the best work of the world has been done against seeming impossibilities. The thing is to get the work done.

Seventy per cent of all patients who come to physicians could cure themselves if they got rid of their fears and worries.

All men have fears, but the brave put down their fears and go forward, sometimes to death, but always to victory.

Do the thing you fear to do and keep on doing it... that is the quickest and surest way ever yet discovered to conquer fear.

If you increase your success by even a mere 10 percent, you have become 10 percent more effective as a leader than you were before.
