Life itself is the thing, not joy or pain or happiness or unhappiness. To hate is as good as to love - an enemy may be as good as a friend. Live for yourself - live your life. Then you are most truly the friend of man. - I am different every day - and when I am eighty, I shall still be experimenting and changing. Work that I have done no longer concerns me - it is past. I have too much on hand in life itself.
