These are two very short books but will help you understand the topics more than thousands of pages on the same topic by countless other writers. In my view, Hart is unquestionably the best writer on military strategy and history. Better than von Clausewitz, that’s for sure (who for all the talk is basically useless unless you are planning on fighting Napoleon). His theories on the indirect approach is life changing, whether you’re struggling with a business or just office politics. I can’t say much more than read these books. It’s a must.
