There are always people at work who are going nowhere and want company. They have endless time to interrupt, chat, complain, regale with stories, and do everything else but complete their key priorities for the day. These people are time vampires. They suck your blood and make you weak.
Do what you have to do to focus on your priorities. Close your door, give them the cold shoulder, find somewhere else to work, or just say, “you know, I’m really busy and don’t have time to talk.” Don’t let time vampires suck your blood.
