For one, I don't feel like there's really a point. I don't really have a job where I ever have to interact with anyone by name, and I don't have friends or even acquaintances, and I don't have any hopes for future plans of any kind, especially none that would involve my name. 

Also, since I have no friends or anyone I even casually interact with, I can't change my name "socially" as a test many people suggest you do before a name change. The only person who I can test it with is myself. And Siri. Which is why I'd need to change it legally, I can't just start going by a nickname for the same "new me" effect, since I have no one who would use that nickname. 

And the other problem, currently the name I've grown most attached to (against my will) is Six. Like the number. I came across the idea of numbers as names and I thought it was neat for some reason, and Six sounded the most 'namelike' to me and somehow it's grown from just a silly thought I was entertaining to the point where I can't imagine being called anything else. 

Should I go with that and do what I want or should I force myself to be a responsible adult (I'm 24) and pick a "real" name? 

And how long do I have to like a name before I can determine whether it's real or just one of those impulsive things I only think I want? (I've had this problem with tattoos. Twice. At least if I do regret it name changes are reversible, and also cheaper, I guess?)
