When we decide to be happy we accept the responsibility to bring happiness to someone else. Some decide that happiness and glee are the same thing, they are not. When we choose happiness we accept the responsibility to lighten the load of someone else and to be a light on the path to another who may be walking in darkness.
What we want is muscles of iron and nerves of steel. We have wept long enough. No more weeping, but stand on your feet and be men. It is man-making theories that we want. It is man-making education all round that we want.
