"The goal is for someone to have at least 10 principles, and they should cover a variety of topics — retention, expansion, working with leaders, whatever. You shouldn't have 10,000 principles. You should have 10, 15. Then no matter where the conversation goes, you're not having to memorize all these things. It's going to naturally come up."
Example
Sample principles: "Every account is at risk until proven otherwise." "Say exactly what you'll do, then do exactly what you say." "Outcomes exist regardless of your product." A practitioner with 10 articulated principles can answer any behavioral interview question by selecting the relevant one and telling the story that demonstrates it.
