Cure for unhappiness: "It's all gonna work out tomorrow, as it all worked out yesterday."

 People who look at the past through rose-tinted glasses are happier than those who focus on negative past experiences and regrets, according to a new study published in the journal Personality and Individual Differences. The findings suggest that persons with certain personality traits are happier than others because of the way they think about their past, present and future.  This jives with studies that show optimistic, grateful, forgiving people live longer lives.  The authors suggest that savoring happy memories or reframing painful past experiences in a positive light could be effective ways for individuals to increase their life satisfaction. Also just doing anything can make people happy, and researchers think this might explain why people get into bad situations like doing drugs, because it satisfies the desire "to just do something!"
