The true meaning of life is to plant trees, under whose shade you do not expect to sit. Be a tree, give fruits, flowers, shade to others without expecting anything from others. Whatever you want from others first you have to give that to others. Whatever you give to others, you will be given in return. If you give love, respect to others then surely you will be given love and respect from others. Thats why we should learn to give good things to others.
