Limit to courage? There is no limit to courage.
Until now I have never really lived! Life on earth is a creeping, crawling business. It is in the air that one feels the glory of being a man and of conquering the elements. There is an exquisite smoothness of motion and the joy of gliding through space. It is wonderful!
I cannot understand why the poets of our day wax indignant at the vulgarity of their age and complain of having come into the world too early or too late. I believe that every man of intellect can create his own beautiful fable of life.
