My first one, a tribal I got in Tech School. Tribals (supposedly) meant the coming of age. I read that back in old indian tribes and whatnot, they'd get one when they killed their first dear, got married, had a kid, so on and so forth. So I had one done when I left the household and did something for myself.
Next one after that is a yin-yang on my wrist. Stupid one I never should have gotten (girl related) but I live with it now and it tells a chapter of my life.
This one is my favorite one. I got it while I was in Japan by a Japanese dude named Yoshi :P Translated, it says "A sound soul resides within a sound mind and a sound body."
