As an author I am encouraged by all the great responses here. In addition to writing a book a year I read about 50. My question for OP: How do you learn anything if you are not reading books? Sure, you can learn a lot about a subject online. When I write a book I spend about 6 months reading everything I can find (including books). Then I organize what I have learned and present it (I hope) in an easy to absorb manner. A reader can learn everything I know about a subject in 4-6 hours. Want to learn about the Cold War? Read Gaddis' seminal book on it. Want to learn about WWII? Read Winston Churchill's five book series that won the Nobel prize for literature? Civil War? Shelby Foote. If history is not your thing what about biography? There are biographies of practically every founder of great tech companies. (Jobs, Gates, Musk). How about ideas? Malcolm Gladwell (Tippingpoint), Michael Lewis (Mondeyball). Or maybe break into reading with fiction. Give yourself a present of the complete Lord of the Rings. If you liked the movies be prepared to love the books. If you hated the movies, no problem, the books are far better. OR science fiction. Read all of Heinlein's books for young adults. Start with Double Star then read Have Space Suit Will Travel. A Door Into Summer speaks to any engineer. Tunnel In the Sky is the classic survival story. When you are hooked on Heinlein read The Moon is a Harsh Mistress; it only takes a chapter to get used to his interesting take on what English of the future will sound like.

I hope you are encouraged by all the great reasons listed in the rest of the comments. I for one live to read!
