The purpose of life is not to be happy. It is to be useful, to be honorable

23-year-old Satyendra Pal teaches slum children under a flyover slab in Delhi. Under the flyover slab meant for the construction of a nearby flyover, over 20-odd children are scribbling on their slates and reading out aloud.

Satyendra's class is open for all the slum children, and allows them to 'pay as they like' for the classes. Satyendra who is a BSc student use the little money paid by the villagers give to pay his college fee and support himself.

Purpose of life is to be happy, people get into pro bono pursuits because it gives them happiness. Happiness is the seed for everything easy or hard anyone ever took. :)
