Apply this simple rule to your conversations: If you wouldn't write it down and sign it, don't say it.
Become the kind of person who brightens a room just by entering it.
Be tough minded but tenderhearted.
What you must do, do cheerfully.
Let the refining and improving of your own life keep you so busy that you have little time to criticize others.
If you need to bring in a business partner, make sure your partner brings along some money.
