Help with tattoo placement?

I'm going to get my tattoo on Saturday and I know that I want it under my collar bone, but I'm not sure if I should get it on the right side or the left side. I'm totally for this whole equal-thing, like I currently have a tattoo on my left wrist, so it would make sense to put it under my right clavicle, but I eventually plan on getting another tattoo on my right wrist. I guess it's all based on what the person likes best, but I have no clue.. someone help me? lol
