“We are, perhaps uniquely among the earth’s creatures, the worrying animal. We worry away our lives, fearing the future, discontent with the present, unable to take the idea of dying, unable to sit still.”

“The future is too interesting and dangerous to be entrusted to any predictable, reliable agency. We need all the fallibility we can get. Most of all, we need to preserve the absolute unpredictability and total improbability of our connected minds.”

“I am a member of a fragile species, still new to the earth, the youngest creatures of any scale, here only a few moments as evolutionary time is measured, a juvenile species, a child of a species. We are only tentatively set in place, error prone, at risk of fumbling, in real danger at the moment of leaving behind only a thin layer of of our fossils, radioactive at that.”

“The oldest, easiest to swallow idea was that the earth was man's personal property, a combination of garden, zoo, bank vault, and energy source, placed at our disposal to be consumed, ornamented, or pulled apart as we wished.”

“When anxiety becomes problematic, most people try vainly to think their way out of trouble. But worry has its roots in the reptilian brain, minimally responsive to will. As a wise psychoanalyst once remarked of the autonomic nervous system (which carries the outgoing fear messages from the reptilian brain), "It's so far from the head it doesn't even know there is a head." (49)”

“The earthly desires men cherish are shadows. There is no true happiness in fulfilling them. Why, then, do we continue to pursue joys without substance? Because the pursuit itself has become our only substitute for joy. Unable to rest in anything we achieve, we determine to forget our discontent in a ceaseless quest for new satisfactions. In this pursuit, desire itself becomes our chief satisfaction.”

“We have negative mental habits that come up over and over again. One of the most significant negative habits we should be aware of is that of constantly allowing our mind to run off into the future. Perhaps we got this from our parents. Carried away by our worries, we're unable to live fully and happily in the present. Deep down, we believe we can't really be happy just yet—that we still have a few more boxes to be checked off before we can really enjoy life. We speculate, dream, strategize, and plan for these "conditions of happiness" we want to have in the future; and we continually chase after that future, even while we sleep. We may have fears about the future because we don't know how it's going to turn out, and these worries and anxieties keep us from enjoying being here now.”
