There is an old saying that anything in this world can be recreated, but not time. You can lose health, you can recreate it; you can lose money, you can make it again. But time passed is time lost. Once we understand this, that inevitably, inexorably, time is limited to twenty-four hours a day, the second step comes, when we will understand how to use that time. Then we will have what we call time consciousness and the ability to guide our life by this concept that time is limited, therefore the most important thing must be done first, the second important thing second, the not important thing not at all.
