Life is like bowling - straight down the lane with a little curve and stay out of the gutters on either extreme
As a kid, you start with certainty. Santa is good. Satan is bad. School is good. Play is a waste of time. (Which really messed you up, because you couldn't help but play, and feel bad at the same time.)
As an adolescent, you rebel. Santa is a cruel joke. The devil is the epitome of independent thought. School's a waste of time. Play is good. (So you indulge in too much of it.)
As a grownup, you come to terms with paradox (hopefully). Everything contains good and bad. Every ideology has a grain of truth in it.
Where are you in your mental, philosophical growth stage?
