Walking up a mountain track, I fell to thinking. Approach everything rationally, and you become harsh. Pole along in the stream of emotions, and you will be swept away by the current. Give free rein to your desires, and you become uncomfortably confined. It is not a very agreeable place to live, this world of ours.
When the unpleasantness increases, you want to draw yourself up to some place where life is easier. It is just at the point when you first realize that life will be no more agreeable no matter what heights you may attain, that a poem may be given birth, or a picture created.
