When you’re not in the best mood, you tend to view everything with less tolerance. This normally results in a confirmation of your viewpoint. When people perceive you to be a grump they don’t go out of their way to be nice or take time to consider your perspective. This then, reinforces your negative opinions. The more you become convinced of your perspective, the more the outside world confirms it. On the other hand, if you sincerely expect the best…

The world will confirm that instead.
