When it gets right down to it, all of life is a fucking fable.
Something happens, you get fucked over, you learn a "lesson".
If you don't learn then that's when the shit starts to suck. The more often you ignore these lessons, the sooner your life starts to fall to shit.
Eventually, if you're not a moron or completely retarded, you begin to learn.
Look before you leap. A bird in the hand is worth two in the bush. He who hesitates is lost. Et cetera, et cetera, et cetera.
Shit's gonna fuck up. You live long enough and something is bound to go wrong. The trick is to try and walk away from the experience with something more than a bruised cheek and a battered ego.
