If you have some idea you believe in, don't listen to the croaking chorus. Listen only to what your own inner voice tells you.
Dale CarnegieSo, to prevent fatigue and worry, the first rule is: Rest often. Rest before you get tired.
Dale CarnegieIf you increase your success by even a mere 10 percent, you have become 10 percent more effective as a leader than you were before.
Dale CarnegieDevelop success from failures. Discouragement and failure are two of the surest stepping stones to success. The successful man will profit from his mistakes and try again in a different way. When you're afraid, keep your mind on what you have to do...if you have been thoroughly prepared, you will not be afraid. We all have possibilities we don't know about. We can do things we don't even dream we can do.
