If you wish to experience peace, provide peace for another. If you wish to know that you are safe, cause another to know that they are safe. If you wish to better understand seemingly incomprehensible things, help another to better understand. If you wish to heal your own sadness or anger, seek to heal the sadness or anger of another.
Dalai LamaYet even the rich have their own kind of suffering, anxiety, doubt, and fear. So in many cases, wealthy people aren't happy! And once those with material wealth encounter small difficulties, their amount of mental suffering is sometimes bigger than it is for those who have faced such difficulties every day.
Dalai Lama
