Getting a Tattoo

For a little while I've been wanting to get a Tattoo but I wasn't sure for definite if I wanted to get the one I planned on.
Anyways I've decided I'm getting it in the end. I'm getting a tattoo on my forearm, it's going to to say Nasyr.
It's a nickname that I made online and now it seems to be a name that even my friends call me.

Nobody refers to me as my real name it's always Nas, girls call me Nassy.
Like when I go to a friends even their parents call me Nas, it's weird but yeah

So yeah guys thats the plan, need to ask though, should I really get this tattoo since it's gonna be there for life.
So advice would be good
