Expose your mental models to the light of day.
Honor, respect, and distribute information.
Use language with care and enrich it with systems concepts.
Pay attention to what is important, not just what is quantifiable.
Made feedback policies for feedback systems.
Go for the good of the whole.
Listen to the wisdom of the system.
Locate responsibility within the system.
Stay humble—stay a learner.
Celebrate complexity.
Expand time horizons.
Defy the disciplines.
Expand the boundary of caring.
Don’t erode the goal of goodness.
