In this constant changing world, time never stands still and so are the circumstances and people around you. No matter whatever power and positions you are holding at the moment, you have to make way for another person sooner or later. All the external object will leave you one by one. However, the only thing which is going to remain with you for ever is your core of human being; the thing which defines your own individuality. That is why you should always aim for personal growth and development in every situation and evolve as a human being.
