Look for what's missing. Many advisors can tell a President how to improve what's proposed or what's gone amiss. Few are able to see what isn't there. ↗
Plan backwards as well as forward. Set objectives and trace back to see how to achieve them. You may find that no path can get you there. Plan forward to see where your steps will take you, which may not be clear or intuitive. ↗
Your performance depends on your people. Select the best, train them and back them. When errors occur, give sharper guidance. If errors persist or if the fit feels wrong, help them move on. The country cannot afford amateur hour in the White House. ↗
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. ↗
