Are you reading people’s signals? Here are a couple of examples.
You are on the phone and sense the people are just not engaged, it’s probably best not to stretch out the conversation. Maybe another time to talk might be better.
You are meeting with someone and you note that they are little fidgety, you don’t sense you have their attention. Again you might be extending the meeting far too long and it’s far better just to end it.
I think people will appreciate your taking these steps, and they might have the tendency to communicate more with you not facing the fear that the next phone call or next visit will be a lengthy one.
