Don't let people sucker you into thinking that your tattoos must have some kind of grand meaning behind them. If you like something, that is good enough... but like it enough to live with it. I'd start by finding an artist you like and then go in and discuss with them what the entire process entails: how much they charge, what sizes things need to be, how the tattoos will change over time, etc... Come up with a few ideas or look at your artist's work to help then I suggest taking a few months to sit on the idea and see how your opinion changes (or not) about it. I have lots of ink and don't regret any of them, though there are some I definitely like more than others.

maybe a unicorn?
