My husband once quipped, “An investment in health is always a winner.” This comment seems to paraphrase the principle advocated by famous motivational speaker John Maxwell, who said that leaders who are already generally driven and result-oriented, must invest in their health so they can give their best at all times and have enough energy in their work. To Maxwell, eating healthily, exercising regularly and resting sufficiently are a must. He wrote that our health determines our quality and quantity of life.
