Energy is a commodity.
we think we have limited time but in reality we have limited energy,focus, awareness.
We need to conserve and invest our energy, like we would money because money is a symbol of our energy.
Invest your energy in things that give you greater return such as exercise and helping others and meditation/prayer.
Do not blindly throw your energy into petty things like gossip, arguments, ongoing family endless problems.
rise above energy wasters and choose to invest your energy for maximum return.
