Ooh, I love talking about tattoos. My oldest ink is about to turn eight years old -- which is remarkable to me. It's been a few years since I've gotten one, and I've been daydreaming recently too. I have a list a mile long, but the next one will most likely involve a classic children's book reference -- either Finn Family Moomintroll or The Dragons of Blueland.
I think the trick to not regretting tattoos is to find an artist whose style you really like, and whom you trust, and not worry too too much about the content/image. If the tattoo is meant to mark a specific moment/rite of passage, you'll always remember the moment even if the tattoo isn't a literal or even metaphoric representation of that moment. Oh, and clean simple lines age better IMHO.
Rachy, you're going to have to think orthogonally if you want a baker's tattoo. Bakers are so covered in tattoos you'll have to poke fun at that through yours. Maybe a big old stand mixer on your bicep? I'm more of a classicist -- I'd probably go with a vintage-looking sheaf of wheat, like you'd find on an old French floursack. (In fact, I may steal that idea for myself someday...)
