You can’t focus on a conversation without looking at your phone every time it buzzes?
Smart phones are awesome. But it would be dumb to lose a friend, a client, or an order because you’re looking at your smart phone during a conversation or meeting.
Looking at your phone in the middle of a conversation tells the person there with you they are not your priority right now.
Wait til the conversation is over and you’ve moved on. Then you can actually use your time more efficiently by answering and/or reading more than one text or email at a time.
