Kick Starting My Future

I have been thinking. What would be the coolest job in the world? My Teacher recommended me to be a tattoo artist. And I love tattoos they always resemble or symbolize something different for each person. I'm super good at art and can draw anything that comes into my mind. But, I'm only in grade 9. What do I need to study? Do I need any more skills other then the ones I already have? I have drawn out 5-6 sketches of tattoos that would look so awesome. I want to get a tattoo of my own. But I'm waiting till I move out of my parents house.

link to my one sketch. not sure how good it is. http://tinypic.com/view.php?pic=2n081p2&s=5
