To educate yourself for the feeling of gratitude means to take nothing for granted.
Albert SchweitzerThe last fact which knowledge can discover is that the world is a manifestation, and in every way a puzzling manifestation, of the universal will to live.

Therefore search and see if there is not some place where you may invest your humanity.
