Once upon a time I saw a Japanese movie - I think it was called Afterlife - which really made an impression on me.
In the world this movie portrays, when you die you spend a few days in some kind of in-between place before you go on to Heaven. Whilst at this in-between place, you are expected to decide upon the one favourite memory of your life on Earth; this is the only memory you can take with you into the afterlife.
So there is this one middle-aged guy who can't think of a single thing. His life has been so boring that for a whole week he can't come up with anything memorable. So the staff lend him a record of his entire life (on videotape, actually), so he can watch the whole boring affair in the hope of finding a memory worth preserving for eternity.
This is where I was inspired. I didn't want to be like that guy, and have a boring life. I also didn't want to be unable to remember all the wonderful moments that I've experienced in my life so far.
Unfortunately my memory is so bad that people have actually pointed that out to me, so I decided henceforth to record worthy moments in a journal.
I kept this up for about six months before I got slack. However, now that I have a blog I can record almost everything going on in my life (except for the really, y'know, personal stuff). When I die and go to limbo-land, I can just read my blog to find my most-favoured moment (at least, as long as it happened no more than about 2 years ago).
Oh, and what happened to Mr Boring? He watched all those tapes and came across a scene in which he and his wife are sitting on a park bench, contemplating the possibility of going to see a movie. Nothing exciting had happened, but it was just an intimate moment between the two of them. And this is what he took with him.
