Nihilism is awesome. Hedonism as well. Sadism can get tricky.
THERE ARE ONLY TWO REASONS WHY ANY CONSCIOUS BEINGS DO ANYTHING, EVER:
1: Out of love. Example, I love spiked Ice Cream. SO, I'm gunna eat some!
2: Out of FEAR. Example: FUCK! If I don't stop drinking at work, I'm gunna get fired! SO, I hide it better XD
Every other reason stems from one of these two, or both. There you go people! A half assed definition of life. NOW LETS PARTY! Figure out how to transmute fear into love, and vice versa, and I think we have a winner. I can feel the powah.
This, and other reasons, leads me to believe that you ARE your own god. Don't let anyone tell you any different! Now go and live.
Capeesh?
