They never forget how you make them feel

In "Think Like A Fan," Twitter's Head Of Music talks about how Drake, Jimmy Fallon, and Kid Rock have gotten traction by using that mindset. And he even quotes Maya Angelou.

Maya Angelou said this “I’ve learned that people will forget what you said, people will forget what you did but people will never forget how you made them feel.” They never forget how you make them feel.

Seems like good advice for a standup set too. Laughs per minute might not be as important as the feeling you leave 'em with.
