I may be offering bad advice here, but I have 8 tattoos and love them all. I am now 44 years old, and started getting them when I was young---I do not regret them. There were some times in the past that I wished I had gotten a different design. but now I am cool with them all. I just got my last work done this past September (tribal piece expanded and reworked on my stomach and chest), October (tribal tattoo on my leg), and December (finished the tribal piece on my chest and stomach).
Here is what I told myself about them early in life. Will I regret them some day? Probably. But, if I don't get tattooed, will I someday regret not having gotten them? Probably---because I would have been curious about having real tattoos. So I did it.
I did the fake tattoo thing for awhile---and I liked the way they looked on me---so I went for it.
Now, about your design you like. There are a lot of sites on the internet offering samples of flash (you know, the tattoo designs), and you can also look on the temporary tattoo sites too, they have some nice designs occasionally.
But as you have heard, and as you probably know, be sure you can live with something on you forever.
I put a couple pics of some of my tattoos on the (getting to know each other) forum under the thread (POST YOUR INK). Check it out if want.
Good luck.
