Time! Who can explain it? “Use it or lose it,” the experts say. All of us have the same amount of it, and it is never enough. There are many sayings about time, such as “Time marches on,” “Time waits for no man,” “Time is money” and “Time is fleeting.” Especially in today’s stressful, fast paced, high-pressure world, time is at a premium. People are constantly checking the time on their wristwatch or smartphone, or their computer—or on the radio or television. Whatever time of life we are in, we seem to be pressed for time to accomplish what we need to do each day.
