I do agree with that.
I've talked to a bunch of people with tattoos that they regret, because the design was stupid, or they were drunk when they got it, etc.
You should be sure about what you want in the present day and what you're going to think about it in 10 years, 20 years, etc. before you get it.
The Autobot symbol I'm going to get tattooed isn't just because I love the Transformers. It's because me and my brothers watched Transformers together growing up, and Transformers reminds me of my brothers.
That may sound corny, but I don't care.
