If you use your life to improve the lives of even five people, that will be the highest fulfillment of your life, no matter how long you live.
If throughout your entire life you make no fortune; travel next to nowhere; obtain a meager education; invent nothing new; are a stranger to fame; lack talent, wit, and charmβif these things are true and yet in the heart of every human who crosses your path you plant a seed of happiness, or, at the very least, you coax a smile from the saddest faces, your life will indeed be the greatest success story ever.
There are only two ways to live your life. One as if all that matters is to have someone love and accept you. The other is as though loving and accepting another person is all that matters. Often, when you choose the second you get the first.
