I think our culture has gotten so skewed. People assume that because you're an actor you want to write a book to exploit your celebrity but my celebrity is only a byproduct of me making movies. I have no intention of being a celebrity.
I did stand-up comedy for 18 years. Ten of those years were spent learning four years were spent refining and four years were spent in wild success. I was seeking comic originality and fame fell on me as a byproduct. The course was more plodding than heroic.
Happiness is a byproduct of function purpose and conflict those who seek happiness for itself seek victory without war.
