All worry is about tomorrow, whether about food or clothing or anything else; but all worry is experienced today. Whenever we are anxious, we are upset in the present time about some event which may happen in the future. However, these fears of ours about tomorrow, which we feel so acutely today, may not be fulfilled. The popular advice, "Don’t worry, it may never happen," is doubtless unsympathetic, but perfectly true. People worry that they may not pass an exam, or find a job, or get married, or retain their health, or succeed in some enterprise. But it is all fantasy. “Fears may be liars;” they often are. Most worries…never materialize.
