Like the other have said, we can’t decide for you. However, I was deliberating like you and I ended up just going to get it done while wandering around Leeds on New Years Eve. I found a studio and got it done there and then because I thought that if I ended up not liking it then I can take it out, yes, it may leave a small scar but who cares? I then met some mates who all said that it suited me and I’ve kept it and can’t imagine myself without it now. So I say: go for it. But it is ultimately your decision. If you’re not sure now, then wait. If you still want it done in 6 months or so, then go get it done. That’s another way that I decide.
