Success does not necessarily mean that we must earn a great deal of money and live in the biggest house in town. It means only that we are daily engaged in striving toward a goal that we have independently chosen and feel is worthy of us as persons. A goal, whatever it may be, is what gives meaning to our existence. It is the carrot on the stick that keeps us striving–that keeps us interested–that gives us a reason for getting out of bed in the morning.  —Earl Nightingale
