Eryn is right. Don't get a tattoo on a whim. Don't pick something off the wall or out of a book in the tattoo shop. Find something (or better yet create something) that is totally unique to you. I have three tattoos, each of which I thought about for at least a year or more before getting them done. It's been nearly 20 years since the first one, and I have 0 regrets!
And please, please, please if you have words inked on your body, use a spellchecker and have the grammar checked by someone who is trustworthy. Nothing makes a person look more stupid than a tat with incorrect spelling or the use of the wrong word ("lose", not "loose").
If you think about it enough, you'll come up with something....
Best of luck,
Ana
