Time is the stuff life is made of. Time equals life, and wasting your time is wasting your life. If you spend one hour on someone or something, you are giving away a piece of your life to that someone or something. Therefore you have to be careful to whom or where you give away your life. If you are not careful with time, time slips away like sand in your fist. Letting time slip away is letting life slip away. Like time and tide, life too waits for none. Life is precious, therefore time is precious. "Lost wealth may be replaced by industry, lost knowledge by study, lost health by temperance or medicine, but lost time is gone forever," says Samuel Smiles. The same minute never strikes twice on the clock of fate. Time and words can't be recalled, even if it was only yesterday. You may delay, but time will not. In this age of rampant consumerism, Thoreau warns us, "The cost of a thing is the amount of what I call life which is required to be exchanged for it, immediately or in the long run." Time is turned into money with which we pay for goods and services. Therefore we pay for things with our life. We don't own things, things own us.
