Strength is Happiness. Strength is itself victory. In weakness and cowardice there is no happiness. When you wage a struggle, you might win or you might lose. But regardless of the short-term outcome, the very fact of your continuing to struggle is proof of your victory as a human being.
You gain strength, courage and confidence by every experience in which you really stop to look fear in the face. You are able to say to yourself, "I lived through this horror. I can take the next thing that comes along."
Because your own strength is unequal to the task, do not assume that it is beyond the powers of man; but if anything is within the powers and province of man, believe that it is within your own compass also.
