Ladies, do you have any specific criteria (besides wanting them) for getting more tattoos?

For context: on May 9th of this year I got my first one--a memorial tattoo for my older brother.

Unlike my other two siblings, who got their memorial pieces (and others) pretty quickly, it was almost three years to his death that I got mine. It wasn't something I was proud of or even particularly happy to get; it was something that caused me unimaginable anguish, and I don't mean the process. I knew well before that the physical part would be nothing in comparison.

Anyway, I'm thinking about getting another (or more) in the future, but my Christian faith has me wary of anything without deep meaning. I worry the more I get the less they will matter. I know they don't have to be meaningful, but I'm just not like that to be honest.

So as the title suggests, what are your criteria for deciding to add pieces? What makes you wait, or decide against getting them? And please: show me your ink! I'd love to see what you have :)
