No offence to you Sir but I would say the initiative should come from you. You have to find ways to do social service rather expecting a call or email from someone like Sarathbabu. He took the initiative and struggled and acheived his dream and so should you. If you feel strongly about social service, get out there, go meet Sarathbabu personally, start something in someplace close to you and work hard to make it a success. That's what Sarathbabu has done and that what he would want you to do.
Just giving your phone and email contact and waiting for someone to contact you will not help.
