Volcel police can't arrest me, I have diplowlmatic immunity 
I am sick of conservative weenies saying tattoos are ugly or self-mutilation or whatever. They're dorks, losers, dweebs even. Tattoos are ART. Hot, sexy ART. Anyone who says otherwise is a repressed nerdlinger that needs to remove the broom from their ass. I see a dude with some sweet tattoos and I'm like damn he's pretty as shit.
I just don't have the confidence in my interests to get one of them rendered on my skin in semi-permanent fashion
I would definitely look back in like two years and cringe at it
I see my older tattoos as contracts with my younger self to be kind and not judgmental towards that younger self. And I think of new tattoos in a similar way. I have an obligation to have just enough foresight to not fuck myself over. So no face tattoos. Nothing edgy or profane just for the sake of it. Nothing political, although that may change now that it’s been almost 8 years since I did a major ideology hop. Did I need several tattoos related to the golden ratio on my leg? No, but they’re also not harmful to me. My younger self did it. They held up their end of the bargain. And that’s kinda nice to know.
Ok but what if younger you was an absolute dickhead
I'm getting one that says
"FRAGILE
STORE THIS WAY UP"
There’s your problem. Don’t get like tattoos about how much you love Farscape or whatever. Nerd tattoos and even political tattoos are, IMO, almost universally boring and ugly. I’ve had great success viewing tattoo artists as illustrators that I’m commissioning to come up with their own interpretation of a concept or image I’ve provided. I never get what I initially envisioned and that’s a good thing because I choose artists who are creative and skilled enough that I love what they come up with. Tattoos are collaborative between the artist.
This is my fear as well. I refuse to do anything I might regret so that later I can look back at my life and regret not doing more.
I debated getting a tattoo for years and years and years and eventually pulled the trigger after seeing a cool photo of a fox jumping into snow, and got that posed fox as my first tattoo like a week later. Utterly meaningless on a personal level, has nothing to do with my interests, but damn if I ain't mirin that fox doing his lil leap
If it makes you happy that tis the most valid reason of all.
