Am I right?

A rough estimation is that I spend 95% of my time being polite and operating my life within the range of being polite and following most social "rules". When I look around, I see many people that just do their thing and push the boundaries and they are the ones who make the breakthrough to "greatness" (i.e. Steven A. Smith, Jim Rome, Charles Barkley, etc.). Should I just give in to my inner desire to follow instinct and live my life in more of a "whatever happens happens but I'm going to do what I want" manner?
