Making good eye contact is a “black belt” trait. It’s a primary indicator of someone’s level of confidence. Timid individuals often look at the ground during a conversation.
Proper eye contact is a sign of honesty. That’s why liars have a hard time looking you in the eyes when they speak. When you make eye contact with someone, it implies that you’re really paying attention.
The best students in any class always make eye contact with their instructor when he’s explaining a lesson. Not only is that respectful, but you also learn better when your eyes aren’t roaming all around the room.
