I agree with Tats, if you don't know what you want don't get one. You have your whole life to get one, so don't rush into it because you can.
I got my first tat, and even tho I wanted another the next day, I took my time to pick out what I wanted next and where I wanted it.
I have 4, I love them all and don't regret any of them. You gotta find something you love and you know ain't gonna come around to bite ya in the a$$. One of my tats has a heart, punctured by a wrench and a piston, because I love to work on things, I always have, and I always will. If you want something meaningful, I'd stay away from the different languages bro, if you want something cool written on your hide, make it in your lang, so everyone can read it, not just latin or chinese people.
Just my 2 cents man. (man these pain killas are some good sh*t)
