1. Be grateful – Some study participants were asked to write letters of gratitude to people who had helped them in some way. The study found that these people reported a lasting increase in happiness – over weeks and even months – after implementing the habit. What's even more surprising: Sending the letter is not necessary. Even when people wrote letters but never delivered them to the addressee, they still reported feeling better afterwards.
充满感激。有研究表明,每天心存感恩的人比一般的人要快乐很多,即使这些感恩的话不说出来,写下来也可以。
