Play too many video games. If my income is the same as it is now, spend too much money on clothes and going out. Do some programming but probably not as much, and only on things I am interested in, such as open source game clients. I currently read a lot (though not traditional books usually, but I have done a lot of that in the past) so I would probably read more. Oh, and waste time on hackernews/stackexchange/reddit.
