" To gain your energy from the right sources means you gain more energy from less; reducing the retarding factors means you have less friction that wastes your energy; focusing your motive power towards the direction of the collective human movement means you use others’ energy to boost your energy.

Gain more energy, waste less energy, spend the energy so next time you’ll need less to achieve more. Increase human mass, reduce retarding force, and increase the force accelerating the human mass. Follow this process with reason.

Gain more, waste less, spend efficiently, learn. "
