Well, I could argue that people are waiting to tell you the principles of their behavior, but you've yet to ask. If people look serious in a coffee shop, it's acceptable to ask them why they look serious. Perhaps the commandments could guide you through the process of extracting and understanding a person's motivations in their own words.

The commandments are meant to help you improve your own behavior. As you improve your own behavior, people will confide more information about themselves in you, and your understanding of what makes people tick will grow. You'll have more intuition about how someone will react to a given scenario. Use the principles to improve your own attitude and behavior so that others pass information to you more easily.

The implementation of this comes down to your clear communication (through both word and body language) that you embody the 25 commandments to everyone you meet. They will receive such a person with great pleasure. As you communicate with them, they'll freely dispense their motivations and dreams to you for study.
