I got my first tattoo after wanting tattoos for about 3 years. That was 4 years ago and, so far, no regret.
For me, each tattoo is a companion. I regularly take care of each one and they each have significance and function to me.
I think the main thing about a lot of people having regrets is that a lot of people, who wouldn't normally get a tattoo, end up getting a tattoo because they see the tattoo culture and are attracted to it. The kind of people who get that one tattoo because they want "a tattoo" and then leave it at that. There's a tattoo culture and certain people just have a mind for that culture and those kinds of people don't usually regret their tattoos. I've simply decided that i'm just not going to regret my tattoos.
For me, its a basic human thing. Cultures all over the world have had tattoo traditions and, in traditions, tattoos mean something. You don't just get a tattoo, you earn it by reaching a certain age or accomplishing something. The first culture that comes to mind is the Iban of Borneo. Though it is waning among the youth, in their tradition, a person gets their first tattoos as coming of age and subsequent tattoos come from reaching certain stages of life, traveling to other places or accomplishing certain things. In this context, the most well known is the hand tattoo for taking a head. There are literally just a few living Iban who actually have that tattoo because no one takes heads anymore. IMO, the tattoos look good and very cool on the old Iban guys, and tattoos are a point of pride for them.
Nowadays, there is actually a big problem with ****** "artists" opening shop and tattooing people.The whole tattoo culture has gotten more appreciation by the mainstream and a lot of people have wanted to get one. As a result, to cash in on the large amount of people who want tattoos now, there are tons of sub par tattoo shops who give crappy tattoos to those people who shouldn't be getting tattoos in the first place.
Anyway, I'd bet this is the reason there is such a high rate of people regretting their tattoos. Higher number of people getting tattoos, for the wrong reasons, more crappy tattoo artists, higher percentage of regret. Also, for the record: no legit tattoo artist will ever let a drunk person get a tattoo.
