Productivity = Focus X Energy

Productivity is a measure of your output against the energy you expend. Focus could be defined as the concentration of energy into an activity. If you have a lot of energy, but lack focus, your energy is used in inefficient ways. If you lack energy, but have focus, you will become frustrated by your lack of output. Focus takes energy as well, but acts as a multiplier of your existing energy when channeled into your activity.
