Too many choices

I recently got an invitation to join gmail. I’m one of the cool people now.
The problem is that I have to come up with a user name. This is where the problem happens. What unique noun/adjective combination describes me. I can come up with ideas, but what do I want to represent me in the fantastic years to come.
If I was less creative (Which is still a possibility. Look at the name of this journal.) it would be easy. I would have at most one idea for a user name, and off we go. But with so many choices open to me, I have brain freeze.
I will continue to ponder it.
