Personally speaking it's ultimately up to you. I don't agree with the fact that it has to be personal and I don't agree that it has to mean something. I've had another very recently and this woman in work said "what does it mean?". I told her that it means nothing - as long as it looks good then thats all that matters.
I also hate the stigmata that goes with getting your first tattoo- being that you'll have loads more. People get more if they want more, I think it's pretty much decided already before the first is inked!
All in all get something you like, and hopefully you can not see yourself regretting as you age. The fact that it may look shit as you age is not a good argument, I mean how shit is your face gonna look at 75 anyway lol. Choose wisely, the pain is not something to worry about that much.
