Ran across this quote and went oh yes.

This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one; the being a force of nature instead of a feverish selfish clod of ailments and grievances complaining that the world will not devote itself to making you happy. I am of the opinion that my life belongs to the whole community and as long as I live it is my privilege to do for it whatever I can. I want to be thoroughly used up when I die, for the harder I work, the more I  live. I rejoice in life for its own sake. Life is no 'brief candle' to me. It is sort of a splendid torch which I have a hold of for the moment, and I want to make it burn as brightly as possible before handing it over to future generations. --George Bernard Shaw

That's all. I fly back from Shanghai to Raleigh in a few hours, and then my work travel for the summer will be done. Phew.
