Dealing with lost motivation?

Okay, so here's the story... 4 months ago I was very motivated to read books, since the gaming part of my life has been going on for a year I wanted to do something else, so I started reading and reading... freud's psychology, philosophy, theology, physics, math, sociology, logic... I read about 300 books heretofore and I still have alot more books I want to read but in the past couple of days I feel unmotivated to do anything... I tried to start playing but I already finished all my games, I tried to write my ideas and thoughts down but im out of thoughts. Any ideas what to do in order to get some motivation? I think the problem is that im starting to look at reading as something I MUST do instead of a hobby, also I think my routine is whats making me bored...
