My tastes at 18/19 were incredibly immature compared to, 25 or 30. I am still happy with my one small tribal tat around my ankle that I got at 18...but I was lucky. It is SMALL. The tat I got on my back at 19. *sigh* It isn't the worst tat in the world, but I was so desperate to get a tat, and I was SO SURE that that tat would rock...well, I have ruined a whole big canvas over a stupid large black celtic design that I didn't even know the meaning of (it is the celtic letter V. Uh...V??? OOPS). I really wish I would have waited until I had a bit more life experience, and a little more maturity before I started putting anything permanent on my body. I know that this isn't the case with everybody, but it seems to be pretty common (go to BME into the IAM section [you have to pay or submit photos for entrance] and you will see tonnes of coverups from tattoos from when people were young).
Really, in the whole scheme of ink on your skin, is a couple of years that big a deal?
There are definitely some people out there that adore their tats that they got at 16, 17, 18, 19...but you are going to find MORE people who are thrilled with the tats they got a little later in life. And further, I couldn't agree more with the quality of work coming out of studios that have strong morals about not tatting anyone under a certain age. I am living proof, sitting here with 2 tattoos done in shabby studios (one in an addition on the guys trailer) that if I would have had patience, maybe even these tattoos would be spectacular
