Principles
Principle #1 → Value = how MANY people you have helped x how MUCH you have impacted their lives
Principle #2 → Focus = inputs that drive you to your goal - everything that doesn't get you there
Principle #3 → Learning = Δ Behaviour / Feedback (invariant to environment)
Principle #4 → Intelligence = How fast you change your behaviour when given feedback
Principle #5 → Mastery = (Deliberate Practice × Feedback × Time) / Resistance
