Pretty much just seconding everything said here.
I got my tattoo about 8 years after I decided I wanted one (because I was underage and no WAY would my parents give permission :p), I’ve had it about 5 years now and still love it, though like delphica I sometimes forget I even have it.
Most of those 8 years I would flip flop about what I wanted, but the last couple of years I settled on what and found a style I loved. When I had the cash after I was legal, I went and got it.
Now I’ve been pondering my next tattoo since a couple months after I got the first one. This one I’ve known the design I want for the last few years, it’s just a matter of coming up with the cash to go to a good place.
This will be my last tattoo though, I don’t want or need a lot of ink.
