You overestimate your reaction to future events

You are terrible at predicting the future. To be more precise, you are terrible at estimating your reaction to events in the future, both positive and negative. It has been shown that people tend to believe positive events like landing the perfect job or getting married will make them much happier than they really will and the same goes for the negative events. The truth of the matter is, however, that your happiness levels will generally stay about the same and they always revert to a steady norm.
