People who don't have as much power as they would like often begin by attributing their difficulties to the environment - competitors, bosses, economic circumstances, and so forth. But in reality people are customarily their own biggest impediment to being as powerful as they would like.

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.

If companies spent more time working on people's feelings of self-worth, they wouldn't have to try, often unsuccessfully, to bribe people to do work.

I do not think anyone who ever saw Lyndon Johnson give a speech would call him charismatic, even though he was one of the most effective presidents in U.S. history. Same with Lincoln. Charisma is only one source of power, and probably not a very important one, at that.
