This is just a way for people to express their feelings after graduation. Maybe my life is not as successful as I expected, but there is one thing I can pat my chest and feel my conscience to guarantee that I am living a satisfying life. Since you have already lived hard for twenty-one years, why not give yourself the courage to live for another twenty-one years? Maybe, twenty-one years later, I will be the happy little man who knows how to live and dream best.
