A very useful exercise to do frequently (maybe not every morning but say, every month), is to write down a list of the most controversial actions (focus on the actions, not the words or the speeches) taken by your favorite politician during the given month. Then go back and visualize the opponent that your guy defeated. Get into the character, practice the way of speaking, the mannerism of said opponent, and slowly immerse yourself into the alternative universe where the other person won and then went on to make the same exact string of actions. It’s important that they be the same exact actions, but it’s OK to come up with different justifications if it helps render this exercise more realistic. In fact after a few times, the need for this exercise lessen, because one naturally stops taking anybody in office too seriously.
