Live for the Moment. Our acts and thoughts and all must be determined by circumstances. Will when you may, for time and tide wait for no man. Do not live by certain fixed rules, except those that relate to the cardinal virtues. Nor let your will subscribe fixed conditions, for you may have to drink the water to-morrow which you cast away to-day. There be some so absurdly paradoxical that they expect all the circumstances of an action should bend to their eccentric whims and not vice vers‰Û¡. The wise man knows that the very polestar of prudence lies in steering by the wind.
