I still have no idea what I want to be when I grow up

The recurring question lawyers ask first year law students when they meet them is something like ‘so what do you want to specialize in?’ The answer I really want to give is something like ‘open source law generalist’, but sadly that isn’t really something that people hire, and probably isn’t something you’d really want to be anyway unless you were an academic- law is a highly specialized profession where ‘jack of all trades, master of none’ is quite true. So at some point in the near future I’m going to have to figure out what or how to specialize, I think… and I have no idea what it is going to be. I’m definitely interested in patents, copyrights, trademarks, antitrust, and a few other things. But none of them yet jump out as something I’d like to pursue single-mindedly for several consecutive years. Definitely something I hope folks around here can help me figure out this summer.
