Dalai Lama: "we must try to do something good, something useful with our lives." Amen

We are visitors on this planet. We are here for ninety or hundred years at the very most.
During that time we must try to do something good, something useful with our lives.
Try to be at peace with yourself and help others share that peace. If you contribute to other people's happiness, you will find the true goal, the true meaning of life.

--The Dalai Lama
