Energy is most usable when it is in concentrated form. The power of energy decreases as it spreads out. How much ever we try finally entropy takes over. entropy is lack of order or predictability; gradual decline into disorder.
Ultimately as mortals all our energy on our body will have to spread out once we die. Now we need to consciously strive our entire life if the energy we are giving out to the world is either positive or negative , optimism or pessimism, are we going to spread love or hatred, are we going to inspire our next generation with our energy.
