Let us first open at the memoranda relating to his daily occupations:
“Plan in the morning the work of the day, and reflect in the evening on what has been done.”
“Carry when walking a book, and a note-book to preserve the ideas, and a piece of bread in order to prolong the walk if need be.”
“Vary the mental and bodily exercises with dancing, horsemanship, swimming, fencing with sword and with sabre, shooting with gun and pistol, skating, the sling, stilts, tennis, bowls; hop on one foot, cross the arms, jump high and far, turn on one foot propped against the wall, exercise in shirt in the evening to get up a perspiration before going to bed; turning, joinery, gardening, reading while walking, declamation, singing, violin, versification, musical composition; eight hours of sleep; a walk on awakening, before and after eating; great sobriety; eat slowly, little, and often; avoid idleness and useless meditation.”
Then come more general precepts:
“Adopt good habits when I change my method of life.”
“Never turn to the past unless to enlighten the future. Regrets are useless.”
“Form resolutions in advance in order not to reflect during action. Then obey thyself blindly.”
“The promptitude of resolutions most frequently accords with their justice.”
“Yield frequently to the first inspiration. Too much meditation on the same subject ends by suggesting the worst part, or at least causes loss of precious time.”
“Suffer slight disagreeables without seeming to perceive them, but repulse decisively any one who evidently intends to injure or humiliate you.”
“One should never feign a character that he has not, or affect a character that he cannot sustain.”
“Self-possession without self-sufficiency. Courage without effrontery.”
“Make intimate acquaintances only with much circumspection; perfect confidence in those who have been thoroughly tested. Nothing to do with others.”
“Question thyself to learn what will please others.”
“No useless discourse. All conversation which does not serve to enlighten ourselves or others, to interest the heart or amuse the mind, is hurtful.”
“Speak little of what you know, and not at all of what you do not know.”
“Why not say more frequently, ‘I do not know’?”
“Speak to every one of that which he knows best. This will put him at his ease, and be profitable to you.”
“Abstain from all pleasantry which could wound.”
“Employ only expressions of the most perfect propriety.”
“Listen attentively to your interlocutor, and so prepare him to listen in the same way to your reply, and predispose him in favor of your arguments.”
“Show neither passion nor weariness in discussion.
“Never direct an argument against any one. If you know some particulars against your adversary, you have a right to make him aware of it to keep him under control, but proceed with discretion, and do not wound him before others.”
“When discussion degenerates into dispute, be silent; this is not to declare yourself beaten.”
“How much modesty adds to merit! A man of talent who conceals his knowledge is like a branch bending under a weight of fruit.”
“Why try to be witty? I would rather be thought stupid and modest than witty and pretentious.”
“Men desire nothing so much as to make themselves envied.”
