6 months is a long time. If I were to do the same, here's what I would work towards:

- Guitar

- Programming language in a paradigm I don't currently work in

- Join a hackerspace and build something small but new every few weeks

- Wildlife Photography

I spend a lot of time in the computer, and while I would not want to give that up, given the time, I'd like to pick up some skills which have bugger all to do with using a computer in a way that I'm used to. I'm already doing two of those things in my spare time, but if I had 6 months, I'd make those my primary focus, and add in the others as my "hobbies".
