I am one, though I forget it sometimes. It was less than 2 years ago that I was going through chemotherapy (which is terribly harsh, and mine wasn't even that intense), and I'm already to the point where I can go without it crossing my mind for weeks.

I'd love to be able to say it changed my life and caused me to understand my own mortality, cherish every minute and live it up. Maybe it did, because I am rather high on life a lot of the time. But I don't know if having cancer had anything to do with that. I'm convinced that appreciating life to its fullest requires a constant and conscious effort, no matter what you've been through or how many times you've been brutally reminded of your own mortality.

Finding favorite books, movies, and music that put the fire back in your eye can really help. My personal favorites are Dead Poet's Society, American Beauty, The Princess Bride, Amadeus, and Dave Matthews. I watch these periodically. They make me happy just to be alive.

And of course there's that someone (you know who I'm talking about) who somehow rejuvinates you whenever you're around them. Combine this with the aforementioned media and you've set yourself up for bliss.

Leave the rest behind.
