The manager, in today's world, doesn't get paid to be a steward of resources, a favored term not so many years ago. He or she gets paid for one and only one thing: to make things better (incrementally and dramatically), to change things, to act - today.

I wrote the book based on a blog that I keep. I also tweet. I don't think that for an incredibly old fart I'm totally behind the power curve. I really believe that the essentials of human relationships remain the same.

Community. A friend started a real estate brokerage a few years ago. By the time she'd added her second employee, she was a pillar of her 35,000-person community. No rule says that only the local banker or car dealer can organize the program to raise supplemental funds for the public library or send the high school band on a well-earned special trip. Participating in community affairs, with time more than dollars, is good business from day one. It gets your name around, adds to your distinctiveness, and, best of all, makes you an attractive employer (which is the key to sustained success).

Accept change as a friend. And don't take yourself too seriously.
