For most systems, the 3 most important elements of production are input, waste and delivery.
The trick is to continually improve the quality of input, reduce the quantity of waste, and increase the velocity of delivery.
The most difficult of the 3 is input.
The most misunderstood of the 3 is waste.
The most critical of the 3 is delivery.
Start with the difficult. You cannot out-exercise a bad diet. Input influences both the magnitude of your waste and the direction of your delivery – up or down.
