Believe you can, and you can. Belief is one of the most powerful of all problem dissolvers. When you believe that a difficulty can be overcome, you are more than halfway to victory over it already.
Norman Vincent PealeAny fact facing us is not as important as our attitude toward it, for that determines our success or failure. The way you think about a fact may defeat you before you ever do anything about it. You are overcome by the fact because you think you are.
Norman Vincent PealeThe capacity to be either happy or unhappy is determined by the manner in which you react to whatever happens.
