I don't read entire non-fiction books anymore but just search for it's summaries or notes.
Most non-fiction books revolve around a few central ideas. Once you internalize this you realize it isn't necessary to read the entire book. You just need to read the summary and notes that someone else has written.
Sometimes a good review on Amazon sufficiently maps the ideas in the book and is all that is required.
Further, you don't always have to buy the books. Your free local public libraries carry a lot of these books and even have the digital version that you can borrow.

For eg : I'm currently going through the book notes that Derek Sivers has written and just posted this last night : https://news.ycombinator.com/item?id=13042438
Another source of (business book) summaries is Actionable Books Weekly : http://www.actionablebooks.com/en-ca/
