Sometime you start a journey which in a way you agree that it’s important for you but you don’t start it for this reason. You started doing it because you want to prove certain people that you can do it. There is nothing wrong in doing that because once you start putting effort and your mind into achieving things you start forgetting about those people slowly. All the anger or the intention of proving someone wrong starts disappearing like water in your hand and you are left with a clear mind and a focus to do something in life. I know this with my experiences and the feeling of achieving an inner peace and physically getting is much bigger experience than anything in life.
Discovering oneself in true sense is achievement, and then you know your weakness or strength. The path is not easy most of the time but once you reach that point then your vision or your goal is much clear.
