This is the true joy of life: being used up for a purpose recognized by yourself as a might one. I am of the opinion that my life belongs to others, and as long as I live, it is my privilege to do for them whatever I can. I want to be thoroughly used up when I die, for the harder I work the more I live. Life is no brief candle for me. It is a sort of splendid torch which I have got hold of for a moment, and I want to make it burn as brightly as possible before handing it on to future generations.

George Bernard Shaw (1856 – 1950)
