The awareness that you need to treasure your time on this side of eternity until your last heartbeat, living a purposeful life, and not wasting your life away, complaining that life is not fair, or living dishonestly to acquiring material wealth.

If only more people were to count their blessings, be it beauty, brain, health, or wealth, there would be less comparing with, and complaining about, others—when they can tell friends and foes that “the God who numbers your days is also the One you’d remember in both good and difficult times.”
