Needing a new nick (handle)

I need a new name. One that means some­thing to the per­son I am now.
I have a bunch of old names, a bunch of names for oth­er con­texts, a bunch of names that oth­er peo­ple have giv­en me and even some names that I just picked up cause I could­n’t be both­ered to think of some­thing real­ly kewl.
The point is I haven’t cho­sen any of the names I use. So how can they real­ly be a reflec­tion of me?
But a name needs to be more than a reflec­tion, it also needs to have a sto­ry, a his­to­ry, a rea­son for being.
So I can’t just make some­thing up.
