Anxiety and worrying are provoked by possibility, not certainty. In fact, many people are less happy when they have more choices, because they have more to worry about. When everything is up in the air, the amygdala becomes more reactive. So, if you tend to worry, reduce your options and make quick decisions whenever possible. As soon as you make a decision, however small, everything starts to feel more manageable.
