- if you are unsure I would say this - wait a year and if you still want it in a year, go get it.
I have 2 tattoos on my wrist (one on either wrist) (8 tats total) and did it before the fad. I do not regret either of them as they have a lot of meaning to me and people don't get them but none of my tattoos were for other people, it was for myself.
As far as covering it for work, it's something to think about. It really depends on what you are doing (as I don't know how they feel about paramedics having visible tattoos). If you have to cover it you have to cover it. It just depends on what lengths you're willing to go to.
