Ask questions that demonstrate (sincerely) that you believe the other person’s opinion is particularly worth seeking out. Focus on his triumphs. Laugh at his jokes. And always, always, remember the other person’s name. Nothing is sweeter to someone’s ears than his own name. At the moment of introduction, I visually attach a person’s name to his face. Seconds later, I’ll repeat his name to make sure I got it, and then again periodically throughout the conversation.
