tattoo problem

I'm 18 and I've always wanted a tattoo since I was younger and not just any but two different ones that I've always thought of and have done doodles of them and I know exactly where I want them but the problem is that o actually want more tattoos but I'm going to college for education and I hope to get into law but I know for a "professional" look no tattoos showing is the way to go I already know that one day I will get my dream tattoos that aren't going to show but I actually realized I want a lot of tattoos what do I do
