I won't take time to repeat all the obvious benefits of physical exercise but will only underscore the well-attested fact that a program of regular exercise increases one's efficiency in every facet of life, including the depth and restfulness of sleep. And the time taken can be minimal; just a few minutes of calisthenics and running in place in one's room or jogging around the yard or block is often sufficient. Exercising doesn't take time. It saves time. Still, few consistently do it.
Stephen CoveyIf we overcome the pull and "get up and get at it," we will have won a victory. We have kept our own resolve. We can then move to other things, for by small means great things are accomplished. Thus, even this one small step is also in another sense a giant leap.
Stephen CoveyWhen your happiness comes primarily from the happiness of others, you know you have moved from a 'me' experience to a 'we' experience. And the whole problem-solving and opportunity-seizing process changes.
