Great thoughts, wherever we find them, have been born in struggle and anguish. So it is in all life. We cannot be of use in the world without cost. What it costs us nothing to give or to do is not worth the giving or the doing. It is those who sow in tears who reap in joy. It is he that goeth forth and weepeth, bearing precious seed that shall come again with rejoicing, bringing his sheaves with him.
