Our prime purpose in this life is to help others. And if you can’t help them, at least don’t hurt them - Dalai Lama
It is good to strive towards a purpose in life, whatever that purpose is, it will motivate and encourage us to work for it. how if that purpose was to help others? helping other will surely rejoice and please the people who get helped, but also will give us a self satisfaction, and thus, inner peace and happiness.
A joyful, satisfying purpose for the giver and the receiver.
