I thought--aside from paying bills and having insurance, which are clearly important to take care of before dying--that you meant experiences to have before you die.
(1) Jump out of an airplane (perhaps this should be the last of the three in case anything were to happen). But there must be something thrilling and entirely unnatural about falling to earth . . . and living. And having that moment where you are glad to be alive, where you feel that you cheated death. I have not done this yet. I'll get to it someday...
(2) Kiss someone that you thought you could kiss only in your dreams, someone who you thought was way too good for you, way out of your league, and who you thought would never want to kiss you back. This I have done (my kid is the result!).
(3) Change a total stranger's life for the better. And then try repeating that every day until you die. We are, I think, obligated to make our friends and family happy (or, at least, happier, or try...). But I don't think enough emphasis is placed on helping perfect strangers, in whatever form that help takes (volunteer work, donations, or something more imaginative). I think this is the only way that our world can get any better. It is tribalism ("it is me and my friends and my family against the rest of the world") that dooms us, I think.
A tiny example (for which I was the beneficiary): once, my wife and I dropped some post cards on the street when we were on vacation once in another country. We thought we had lost them forever. We found out that the postcards got to our friends--apparently a perfect stranger put postage on them, and wrote, in English, "A letter written must get to its destination."
I am still trying. I don't do this every day (I don't even come close), but I'm trying.
