i was the same as you.
things happened in my life that meant i was pretty sure i'd never regret the first one i got.
after getting one i think its real easy to hooked. you don't have to have deeps meanings for each one. finding a good artist to help you out is the trick. i was lucky in that im friends with a good one, so i naturally went to him first.
just check a few shops out and get some ideas.
im afraid of the pain... in places... haha.
before my band went to the US, our singer came to my house, and got an eagle flying with bolt cutters tattooed onto one side of his belly. top of the drawing hits the floating ribs, and the other side goes half way across his belly, and the bottom goes to his waist. he was lying on my bed getting it done, punching the bed, yelling, stopping every 2 mins, chain smoking... it looked pretty painful!
i hear getting your knees done sucks too.
