I've been reading two hours a day consistently for the past half year. I generally read with purpose and settled into a daily routine of reading a book on business, a book on programming, and a book for fun. It works for me.

I also found that non-fiction is more interesting than fiction. Fiction needs to be believable, non-fiction doesn't. Non-fiction captures a complex, layered reality with characters that are often at odds with others and even themselves. Sometimes they randomly died off, sometimes they show up again in unexpected places. A fiction author would have to be an absolute master to create such a complex world.
