100% this. I have a tattoo on my forearm that just makes me happy to look at. It is nearly always partially in my vision while working due to its location. If I am having a bad day I can just look at it and smile. It reflects an important part of me.
The mental health benefit of that, has been incredibly noticeable in my day to day.
Could I have done something similar with a picture on my phone or something? Sure. But this clearly has a huge impact on my mental health so why not get it tattooed. Also my 5th tattoo so it wasn't a crazy idea for me.

That said, there are some objectively bad health outcomes that can come from getting tattoos [1, 2]. Not that they necessarily will.
