A nything is possible or shall we say nothing is impossible. V Kathiresan's story proves that. This school dropout, who used to work as a driver for A P J Abdul Kalam, ensured that his dream turned into a reality at the age of 47.

A native of Vadachennimalai in Tamil Nadu, Kathiresan has come a long way with sheer determination. From being a school dropout, he went on to complete a PhD in history and was appointed a lecturer at the Arignar Anna Government Arts College in Vadachennimalai last year.

"I can never forget the role played by Kalamayya (sahib). I worked as a driver with him for five-and-a-half-years and during those long drives, I used to talk to him about my aspirations and dreams."

"One day while driving, Ayya suggested that I should resume my studies. He told me that the best way to go about it was through long distance education. Ayya used to lecture several students about the importance of education. I used to listen to him speak and got inspired."
