Having realistic expectations could make you happier than being over-optimistic
There are fairly good arguments for optimism and pessimism both. Optimists, who see the best in everything, are likely to have a sunnier disposition; pessimists, on the other hand, would argue that their negative expectations never leave them disappointed when the worst actually happens.But in the end, it might be realists who win out. According to a study published in Personality and Social Psychology Bulletin, being realistic about your life outcomes is likely to make you happier than overestimating them.
