• Put your devices away.
• Take off your watch if you're going to keep glancing at it.
• Make eye contact.
• Lean in.
• Nod your head when you understand or agree.
• Stop thinking about what you want to say.
• Take notes on paper, if it's appropriate.
• Ask questions when you don't understand.

This isn't meant to be a formula or a complete list. It's just a flavor. If your methods taste similar, you're on the right path.
