Let me share to you what Kuantzu wrote:
"If you give a man a fish, he will eat once. If you teach a man to fish, he will eat for the rest of his life." It is better to teach someone on how he can make a way of living than just by sharing him your food. That way he will work and earn on his own.
"If you are thinking a year ahead, sow seed. If you are thinking ten years ahead plant a tree." Sometimes we have something that others don't have. We should realize that we are blessed and be able to share whatever we have to others.
"If you are thinking on hundred years, educate the people. By sowing seeds, you will harvest much. By planting a tree, you will harvest tenfold. By educating the people you will harvest one hundred-fold."
