Normal to be nervous?

So, i'm sceduled tomorrow at noon to finaly get tattooed. But now, im not having second thoughts, but I am quite nervous. I guess it's a ,little mox of excited/anxious and nervous, actually =P. First one, as ive already said before, so maybe thats why. It's just kind of nervewracking to think that this thing will be on me for the rest of my life. I really like it and everything, but still =P. Is this pretty normal, especially for a first timer? Thanks.
