People are often incorrect when estimating how positive or negative life events will change their long-term happiness. It is easy to imagine feeling permanently euphoric after events such as winning the lottery, being asked on a date by an attractive celebrity, or being offered a dream job, or to imagine feeling permanently miserable after a disabling accident or the end of a romantic relationship. For example, long-suffering fans of the Chicago Cubs baseball team, whose team had not won a World Series championship since 1908, thought they would feel permanently elated when the team finally won another World Series in 2016.
