When you have harmonized yourself to a frugal provision for your bodily needs, do not pride yourself on that; and if your drink is water, do not take every opportunity of declaring I am a water drinker. And if you wish at any time to inure yourself to labour and endurance, do it unto yourself and not unto the world, and do not embrace the statues, but some time when you are exceedingly thirsty take a draught of cold water into your mouth, and spit it out, and say nothing about it.
