My overall recommendation: for decades corporate policy manuals and HR departments have told people they are responsible for their own careers. It's about time people really heeded those warnings.

I am not sure any of the material in Leadership BS would be helpful for small companies and certainly not their owners. Of course, even owners have bosses and need to worry about keeping their jobs - so Power might be more appropriate.

Today, if the CEO thinks it's a good idea, it's done everywhere; if the CEO thinks it's a bad idea, it's done nowhere. We ought to be more agnostic and open to learning things that we didn't expect - and the only way to do that is to try things and be open-minded about how well they are working. And third, evidence-based management involves reading and learning - just like doctors do - and to do so not just in school but afterward, as well.

To paraphrase the late management thinker and writer, Peter Drucker, thinking is hard work, which is why so few people (including actually senior managers) do it. Once there is some "conventional," seemingly-reasonable story, people just accept it and don't ask, "is this actually true? Is it consistent with the data?" And this extends to the highest reaches of organizational life.

Point at solutions instead of at each other.

Part of strategy is figuring out what you're good at, figuring out what you're not good at, and then getting yourself in position to succeed by doing mostly what you have a competitive advantage doing.

I don't think eliminating the knowing-doing gap depends on the amount of knowledge around. It depends much more on people's attitudes and intentions - do they actually want to turn knowledge into action, or just go through the motions of acting as if they are busy or are accomplishing something.
