This quote has so much to teach us. What is tells me is that time should be taken seriously. I like how it contrasts the two antonyms "shorter" and "longer" to prove a point. It tells us that we should take advantage of the time we have. The longer we wait, the shorter the time we will have to advance later on. Time is of essence, and we should strive to be active, and not let it pass us by! We should have a "shorter" wait for the future, so that it may be "longer" in the long run.
