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.
Don't necessarily avoid sharp edges. Occasionally they are necessary to leadership.
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.
Be precise. A lack of precision is dangerous when the margin of error is small.
