I haven't really done anything til now.But I surely want to do something to my village/town where I grew, and to the country at large when I am capable of doing something but this doesn't keep me away from extending a helping hand to those in the need in any which way possible.After all small efforts count too.
It is a nice question.I had taught many students from my village (Some free and some paid).Also a lot of students had given career guidance.Still eagerly looking for a charity work.
