4. Honour Your Word
A person’s true value is calculated by the degree to which they keep their word. If you say you will do something, you must do it.
In business, if you quote a price, you must honour it even if you end up losing money.
If you say you will be somewhere at a certain time, or that you will call someone later, you must do everything you say you will do.
Your word becomes your own personal commandment to yourself as if spoken by God.
