One wish?!?! Come on, you don't expect loquacious old Dread to give one answer, or even a simple one, do you?
Here's what I would wish for:
1. Inner peace. If I can't have world peace, the best that I can do is have peace within myself.
2. Wisdom and compassion. So many of think that we're smart because we went to college, but believe me, that is no guarantee of actual intelligence. I know of too many folks who didn't go to grade school, even, but are very wise, indeed. I also want to have more compassion and understanding than I already have.
3. Long life. Not necesarily immortality, unless I get to keep all of my faculties and my independence. To quote CEO Morgan: "I plan to live forever, of course but barring that, I'd settle for a couple thousand years. Even five hundred would be pretty nice." Now, that would be cool!
4. To take it all back. Too bad life isn't like a Civ game, where you can save and reload. All those mistakes and dumb things that I did...
5. To live comfortably. I don't want to be rich. IMHO, it's obscene to have tons and tons of money while others starve. I do want to be able to live comfortably, not worrying about bills or rent, or where my next meal is coming from.
Ok, enough for now...
