For those of us who believe in the Second Coming of the Savior, the speed with which events can unfold (as evidenced by the collapse of communism in Europe) should not be lost on us.
If you don’t set concrete, measurable, achievable goals, you will never achieve them. Time is all we have in this life: birth to death. So, we measure everything by time, and we put in the time on those things that are (1) important to us; and/or (2) immediate to us.
