Most of us will never know our true capacity for achievement because we never challenge ourselves to perform at our best every day. This truism becomes apparent when you are presented with an opportunity that really interests you. No matter how busy you may be, somehow you will find the time to pursue it. Conversely, duties that have little appeal for you are easily postponed and eventually forgotten. Busy people are not procrastinators. They know that life, as John David Wright once observed about business, “is like riding a bicycle. Either you keep moving, or you fall down.” The most effective people have a sense of urgency. They set deadlines and force themselves to establish priorities. Even if your activities don’t usually require strict deadlines, set them for yourself. You will be amazed at how much you can accomplish in a short time — if that’s all the time you have.
