I have personally learnt many lessons from the movie. One that a person should not run behind success, he should become excellent in whatever he or she does. Secondly the world has enough and more doctors and engineers but the world needed people from other field. Thirdly we should choose our careers according to our strengths and weakness and not what people or the society will think about us. For this there is a very good dialogue in the movie which says that imagine if Sachin Tendulkar would become a singer and if lata mangeshkar would be a cricketer. They are were they are today because of the fact that they followed there heart and not cared what people think about them.
