No one can make you feel inferior without your consent. Confidence is contagious. So is lack of confidence. Never let yesterday use up today. Look at a stone cutter hammering away at his rock, perhaps a hundred times without as much as a crack showing in it.
Life is a succession of moments.
To live each one is to succeed. A wise man will make more opportunities than he finds. Doubt is a pain too lonely to know that faith is his twin brother.
