The world is so unhappy because it is ignorant of the true self. Man's real nature is happiness. Happiness is inborn in the true self. Man's search for happiness is an unconscious search for his true self.
If I fail, I try again, and again, and again. If YOU fail, are you going to try again? The human spirit can handle much worse than we realize. It matters HOW you are going to FINISH. Are you going to finish strong?
