My strategy has been to block out an hour in the evening where I go do some reading. I find having a routine really helps, often I'll read more once I start, but this way I know I'll read at least an hour each day. Once you get the habit formed, you start doing it naturally. Another thing I found is that it's ok to abandon books. Sometimes a book just doesn't do anything for you, and I used to try and push through, but realized there's really no point reading a book you're not enjoying.
