The Hard Thing About Hard Things is a decent management book aimed at small-business owners. It purports to talk about the kinds of things that are not normally discussed in management books.
If you follow the formulas set out in most management books, you never get into trouble. Of course, real life is not like that, so Horowitz's book is mostly about how to get out of trouble when you've already painted yourself into a corner. He has rich personal experiences, having been in numerous managerial positions (including CEO) of public companies that have been both successful and unsuccessful.
Sometimes he had me scratching my head; I wouldn't necessarily always do what he suggests. But what I love about books like this is you get to absorb the experiences of another, even if you don't always agree with him.
