Whatever you do, you need courage. Whatever course you decide upon, there is always someone to tell you you are wrong. There are always difficulties arising which tempt you to believe that your critics are right. To map out a course of action and follow it to the end, requires some of the same courage which a soldier needs.
A man should learn to detect and watch that gleam that flashes across his mind from within, more than the lustre of the firmament of bards and sages. Yet he dismisses without notice his own thought, because it is his. In every work of genius we recognize our own rejected thoughts they come back to us with a sort of alienated majesty.
