I think you go through a period as a teenager of being quite cool and unaffected by things.
Each one has to find his peace from within. And peace to be real must be unaffected by outside circumstances.
I've been trying to take this journey over the last four years of getting away from playing manipulative and villainous characters and playing characters that are affected by what happens to them as opposed to unaffected.
No matter how full a reservoir of maxims one may possess, and no matter how good one's sentiments may be, if one has not taken advantage of every concrete opportunity to act, one's character may remain entirely unaffected for the better.
You must be a lotus, unfolding its petals when the sun rises in the sky, unaffected by the slush where it is born or even the water which sustains it!
