There's no one more powerful or impressive than someone who gives you their full, unwavering attention. People who listen passionately and energetically, who are fully engaged in a conversation, are unforgettable. Ironically, you can win the day (or the meeting, or any interchange, for that matter) not by talking but by listening. So this week catch yourself in any conversation - at work or at home, in person or on the phone - when your mind wanders, when you feel the urge to check your Blackberry - or simply check out. Stay focused, stay on point, stay fully engaged. You'll be amazed at what new possibilities you'll discover - and how the balance of power will shift in your favor. Try it!
