Confused about my career

I don’t feel fulfilled at Isilon. I haven’t quite figured it out - I have fantasies of being in Japan, fantasies of being in graduate school, fantasies of being involved with Mathematics - but I don’t know if those are just tools to escape the present or real dreams. I don’t know if I would be at Isilon if I wasn’t worried about finances. What if I had all the money in the world? What would I do? This is something very serious to think about.
