Don't just go out and get a tattoo otherwise you'll regret it. When I was 16 I was this close to getting an anime character tattooed on my shin. What may seem cool to you now...well I don't have to finish that sentence.
A few things are important;
1) Placement: Probably not a great first impression on a business client in 10 years time when you turn up at a meeting with neck tatz.
2) The message: Tattoos are metaphors, if you're going to get a tattoo make sure it has a meaning. Whether it's symbolic of friendship, or a belief you hold, etc.
3) The place you're getting it done: Do not go for a cheap parlour, you may end up regretting it.
As for a design, well once you figure out the message then the design should follow suit.
Solid advice. Here's my list of design no-no's:
1. No names, unless they are blood relatives. GFs / wives can come and go. Family is forever.
2. No nudity.
3. No logos, unless you were personally part of whatever group the logo is for. I saw an old-school Metallica logo across a guys back once - might have been cool around the time of Justice / black album, but now, I'm thinking they regret it.
4. No skulls. This one is more personal preference.
I can't say enough about placement, either. I worked at a place for nearly a year before people knew I had both biceps done. If you're under 18, keep it somewhere it won't affect your chances for political office. ;-)
And, as for shop selection, ensure they're using one-use needles every time. And sterilizing their equipment. Any reputable shop should be willing to show you what they do and show you the new needle when they start. If they won't, walk.
Lastly, sit down with your chosen artist and talk design. It's forever, so make sure you get it done right.
Oh - and tip the artist a few bucks if they don't own the shop.
