Everyone does it.
Every company I have ever consulted with – high-tech, low-tech, service, manufacturing, blue-collar, white-collar, whatever – takes on too much. Too many strategies, too many objectives, too many initiatives, too many projects, too much.
And the consequence? Many of those things fail. Do this repeatedly and you create a track record of failure. An expectation of failure. An acceptance of failure. A culture of failure.
