Leading by example means doing it yourself before you ask others to follow you. That is the hallmark of an excellent leader.
To lead by example one has to have a personal discipline and consistent application of principles of success.
My role is to act as the "bouncing board", impassionate, rational reflector of thoughts, giving advice that is useful, practical and helps in changing behavior for both short term and long term impact.
My work ex: I have worked with Bharat Petroleum Corp.
