All human needs break down into two categories. Internal needs are
for yourself, and External needs are for other people. Since we
are interdependent, other people’s needs are part of our own
needs.
Since the success of our lives and the health of our being is
determined by how well and how completely we get out needs met,
and if needs are met with limited energy, then everything hinges
on efficiency and balance.
We must distribute our limited energy evenly between our various
needs, giving enough to our survival, achievement, and
experiential categories, and ensuring that we give enough to other
people. Above all else, we must strive to waste as little energy
as we can, and stretch our fuel as far as it will go, so as many
needs are satisfied as possible.
