A short term view will lead to a partial and perhaps twisted view of the whole picture. A crucial element may be missing. We may not be running the entire race. A friend of mine described a colleague as great at running the "ninety-five yard dash." That is a distinction I can do without. Lacking the last five yards makes the first ninety-five pointless. In fact, serious runners thing of it as a 110 yard dash so that no one will best them in the last few yards. You've got to think beyond the whole.
