What is the 10 10 10 rule in sales?

Excuse me, could you elaborate on what exactly is meant by the "10 10 10 rule" in the context of sales? I'm intrigued to understand how this rule might guide decision-making or strategy in the sales process. Could you please break it down into simpler terms and perhaps provide an example or two to help me grasp its significance? I'm particularly interested in how it might differ from other commonly used sales principles or methodologies.
