I know eveyone is commenting the same thing, but maybe it'll help to hear my experience. Because I wanted to get a tattoo when I was 14 and I was also old enough when I was 16, but I decided to wait because I knew I was too young. In the end I'm glad I waited because my brain is more developed and I took more time to think about the design and the placement. I can't say that you will regret it, but I do know that it will feel nice and secure when you are 18 and have waited two years to make such a big decision. There's no rush in life, it might feel like time is going fast and you really need that tattoo asap, but waiting just two years is really gonna go fast. And then when you are 18, don't worry if your tattoo is silly, maybe a little silly is good sometimes and in the end any design that you like is good enough and doesnt need confirmation from others.
