exactly, a high position is required(but not necessary always....as i know i'll not be serving like an IAS, IPS or any other high profiled citizen.....but have found the way to bring some change that could be possible at my part).....trying all my little efforts that i could as per my capabilities, potentials and desire.
regarding change....a little change mean a lot to me (which then can be maintained/progressed further with the base already formed)
All the Best to U as well
