I don't really "live every day like it's my last."
You see, I'm one of those people who wants to go out with a BOOM! or a CRASH! or maybe even a POW! Not literally of course. I'd prefer to not date my exclamations.
The way I see it is that there's not a huge point in anything, so screw it. I want to be remembered, but not forever. The idea that a couple thousand years from now no one will remember me is completely foreign and interesting to me. Newspapers for a week, news for a month, talk for a year, and done. That's a big enough BOOM! for me.
