The fact that I'm still alive. That's the only raison d'etre I need, and I swear to all of the gods that may be, if there's a way to extend or prolong my life to the point where practical immortality can be reached, I will implement it. I don't care how much it costs. I'd rather live forever and enjoy the hell out of life than die with only a few of the possibilities available to me explored. Doesn't mean I look down on people that'd rather just live life to the fullest and die when the time comes, only that I'm determined.
