Well, I don't know if this actually counts toward your question as such but the one thing I've always wanted to do is to be with a lady that truly loves me for me! Not for what I have or can do but simply love me as the person I am. I think I'm close to achieving that goal this late in my life.
Come outta my car on red light, turn on the tape and dance my heart out!
Where to start? In terms of travel, I really want to go to Italy, Canada, Denmark and Iceland. I also really want to see the Northern Lights and the Southern Lights, but I don't know where specifically I want to go to see them.
Other stuff I want to do includes: Having my fortune read, learning to play the drums, going roller skating, learning to read tarot cards, owning a Lancia Stratos and being happy.
BUT, I know you asked for one thing, so if I had to pick just one, I'd say that I really want to be happy.
Edit: I know your question says about the one thing you've never done before, so I just want to say that of course I've been happy before, but it seems like such a long time ago that I don't remember what it's like, so that's why it is one of my most important ambitions at the moment.
I'd like to go ice skating.
I've always wanted to meet my doppelganger(s). I think it'd be an interesting experience!
Iv'e always wanted to go to Japan :-)
I always wanted to be a writer.... Get published somewhere some how. However a more simpler goal I have just announced to my husband I want to do sometime is go see the stars....... Those kinds of stars a city girl only hears about in movies and stories! I want to see the sky filled with millions and millions of little twinkling stars! :0)
