The best advice I ever got was: "Always question everything."
The easy way out in any situation is to accept things as they are. To question others takes courage; to question yourself takes honesty. To question is to fight convention, to question is to invite change, to question is to understand. But it all will help you to find new answers, to open new possibilities.
We don't always have clear answers and we don't always agree with existing ones. Every person who has achieved greatness in the world has put up their hands and asked questions. Gandhi questioned violence, Buddha questioned desire, Christ questioned revenge, and the Wright Brothers questioned gravity.
So question fearlessly, you'll find yourself finding answers you never thought of. My father, Mr Prakash Chauhan, gave me this advice before I started working.
