When we let a day go to waste, we tend not to immediately mourn as we should, in part because we subconsciously relish the power (and implied temporal abundance) of being able to waste it. It's easier to accept a loss in the act of letting go, far easier than when memory discovers its creative side and eras of our life cross the borderlands of "what could be" into "what could've been," finding themselves completely within memory's jurisdiction. What has dropped from careless hands finally loses all possibility of a renewed grip.
Friends, to leave your sails furled during the breezy days, years, and periods of your lives always entails great risk! There is no recycling the perfect moments of opportunity!
