I cried because I had no shoes until I met a man who had no feet.

For, after all, every one who wishes to gain true knowledge must climb the Hill Difficulty alone, and since there is no royal road to the summit, I must zigzag it in my own way. I slip back many times, I fall, I stand still, I run against the edge of hidden obstacles, I lose my temper and find it again and keep it better. I trudge on, I gain a little, I feel encouraged, I get more eager and climb higher and begin to see the widening horizon.

I believe we should so act that we may draw nearer and more near the age when no man shall live at his ease while another suffers. These are the articles of my faith, and there is yet another on which all depends — to bear this faith above every tempest which overfloods it, and to make it a principal in disaster and through affliction. Optimism is the harmony between man's spirit and the spirit of God pronouncing His works good.
