Well, gotta be honest, I too live right now because I'm in love. Not in a relationship, mind you, that right now is still not possible and I'm cool with that, but hopefully we're going to try in the future. I live for that hope, that it might become something wonderful.
If not, well, tough, I'll always end up with a great friend no matter what happens between us. But that doesn't mean that I don't hope that the best option actually comes true. We'll have to see, but I'm optimistic.
Other than that, there is a wonderful world out there from which I have still barely seen anything and that urge to explore, learn and see is quite important as well.
And of course fiction, I just love to see what the human mind can come up with. I just returned from watching Avatar, and heavens it truly is a fantastic movie. I also live to see those creations.
