How do you teach your puppy the meaning of the word NO?

Question from Spencer: How do you go about teaching your puppy the meaning of NO. I'm raising a Border Collie and she can be very persistent in doing what she wants to. I'm raising her as close as possible to your methods and what I have seen Cindy do. My one concern is about is about teaching the NO. What I have been doing is just staring at her and saying NO repeatedly. Then when she complies, I stop saying it and break the stare. Is there any more you can teach me on this subject until she is old enough to be 'leash popped' as a correction? She's 11 weeks old, so most NO's are about jumping on the ExPen, nonsense barking, or peeing inside.
