Would you trade your life?

I spend a lot of time inside my head. Jumping from deep conversations with myself about life, love & and everything else, to random assessments of how my life would be, if I was someone else. 

I think about lives I could have changed, businesses I could have built, wars I could have fought and people I could have know. It's often a welcome break from reality. But the reality of my existence always trumps my cognitive flights of fancy. Don't get me wrong, my life has been great up to this point, but I can never seem to escape the question of how to become something more/different than the person I am today.

Do I just take charge and change direction, or will fear of the unknown ultimately hold me back? Do I incrementally adjust or is that a sure fire way of ensure I never diverge entirely.

So man questions. Still searching for answers. Still wondering if I would trade my life.
