" Think of your life as an hourglass. You know there are thousands of grains of sand in the top of the hourglass; and they all pass slowly and evenly through the narrow neck in the middle. Nothing you or I could do would make more than one grain of sand pass through this narrow neck without impairing the hourglass. You and I and everyone else are like this hourglass...if we do not take [tasks] one at a time and let them pass...slowly and evenly, then we are bound to break our own...structure. "
