The one thing that life teaches us, if we truly live, is that everything is mutable, nothing is certain, and change, radical change, is always looming. Living is then navigating our own course through this sea of uncertainty by being supremely decisive, not with an ambitious mind that plans and thinks ahead, but with a heart that can only be true. What stops the heart being true is fear of death. Every moment then presents us with a dilemma: to be true and die or to be false and survive. The human race took the wrong turn when it chose the latter.
