Amidst all the clutter, beyond all the obstacles, aside from all the static, are the goals set. Put your head down, do the best job possible, let the flak pass, and work towards those goals.
Congress, the press, and the bureaucracy too often focus on how much money or effort is spent, rather than whether the money or effort actually achieves the announced goal.
Don't be a bottleneck. If a matter is not a decision for the President or you, delegate it. Force responsibility down and out. Find problem areas, add structure and delegate. The pressure is to do the reverse. Resist it.
Don't divide the world into "them" and "us." Avoid infatuation with or resentment of the press, the Congress, rivals, or opponents. Accept them as facts. They have their jobs and you have yours.
