(CNN)During a tech event in San Francisco last month, former President Barack Obama offered some advice on how to govern in the Oval Office. “Make sure you have a team with a diversity of opinion sitting around you. The other thing that’s helpful is not watching TV or reading social media. These are two things I would advise, if you’re our president, not to do,” he said. “It creates a lot of noise and clouds your judgment.” Obama went on to explain that worrying about polls, or the opinions of certain people, could “sway your decision-making in an unhealthy way.”
