One's universe as they see it is simply an expression of data gathered and processed by the mind.

But that "blow-your-mind-if-you-think-about-it-too-much" crap outta the way, I believe that the quality of one's life and the satisfaction they get out of it depends on their willpower. You can value or believe in whatever you want, but without the willpower to act on those values and beliefs, they're completely pointless.
