This is the real secret of life -- to be completely engaged with what you are doing in the here and now. And instead of calling it work, realize it is play.
Darwin abolished special creations, contributed the Origin of Species and hitched all life together in one unbroken procession of Siamese Twins, the whole evolved by natural and orderly processes from one microscopic parent germ.
Life is perpetually creative because it contains in itself that surplus which ever overflows the boundaries of the immediate time and space, restlessly pursuing its adventure of expression in the varied forms of self-realization.
No one imagines that a symphony is supposed to improve as it goes along, or that the whole object of playing is to reach the finale. The point of music is discovered in every moment of playing and listening to it. It is the same, I feel, with the greater part of our lives, and if we are unduly absorbed in improving them we may forget altogether to live them.
