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.
