The only real power one has is the power of persuasion. The less you know about something the simpler it seems. Important decisions require at least one night's sleep. Decisions made without all the facts are guesses. The most important thing a manager does is people picking.
Lies are hard to remember.
There is nothing more critical to true success than openness, honesty and integrity. Those that don't solicit and listen to advice are destined to be unsuccessful. What is given cannot be taken away. Meddling after responsibility is delegated and accepted, provides a built-in excuse for failure. Unwritten agreements are soon forgotten.
