Science shows, however, that high expectations are frequently both erroneous and toxic.
Toxic because they may lead to letdown and even depression.
Erroneous because we focus too much on the salient high points (e.g., the vacation, voyage, or feast) and too little on the quotidian chores, uplifts, and hassles that are what influence our happiness the most. Researchers have found that annoyances are worse than calamities and that daily delights impact our well-being more than major events.
Unfortunately, the holidays are replete with daily trials, strains, and aggravations.
