Throughout his successful life, William Pryor Letchworth lived by a set of "Rules of Conduct" which he formulated when still a young man. As Larned writes "(Letchworth) either formulated or borrowed and adopted the following 'rules of conduct' ", a copy of which, dated 1842, has been preserved"

Here is the list as it appears in Larned's book:

• Rise at 6 o'clock.
• Breakfast at 6.30.
• Dinner or Lunch 12.30.
• Supper at 6.30.
• Retire at 9.30.
• Attend divine service once every Sunday.
• Tell the truth under all circumstances, when necessary to speak.
• Never wound the feelings of others if it can be avoided.
• Strive to be always cheerful.
• Review the actions of the day every night, and apply to them the test of my conscience.
• In business affairs keep in mind that "procrastination is the thief of time," and that "time is money."
• Be temperate in all things.
• Strive to speak kindly, without giving offence, always with coolness and deliberation, having due regard for the view of others.
• Aim at a high standard of character.
• Attempt great things and expect great things.
• Aim to do all possible good in the world, and so live as to live hereafter and have a name without reproach.
