The trick to not getting regrettable tattoos is to choose something that symbolises something of great significance in your life.
For example, I have what some would consider a regrettable tattoo. It's a band logo. It seems like a dumb decision until you hear the reasoning: it's the first band I became a huge fangirl of, and the only "big" concert my mum and I were able to attend before she died, so that logo is full of fond memories of my mum and I in the first and last mosh pit we were in together. <3
If it means a lot
to you, do it! If not, think about it for a few years, it's not like the opportunity to get it will be gone, and it will
be there forever.
