　在生活中每个人都希望事事顺心，不想有任何不幸的事情发生在自己身上，但有科学研究结果告诉我们，不幸能让我们更坚强。

　　A multiyear study of nearly 2,400 surveyed subjects found that those who experienced negative life events reported better mental health and overall well-being than those who did not. The study is published in the Journal of Personality and Social Psychology.

　　It seems there’s a sweet spot, where a certain amount of struggle is good and produces a toughness and sense of control over one’s life, but anything above or below that amount is correlated with the inverse: Distress, anxiety, and feelings of being overwhelmed.

　　While the authors note that its impossible to identify this sweet spot of adversity, their research suggests that around two to three events might provide the ideal amount of protection from future stress and unhappiness. Yet they are careful to note they are not endorsing anyone to go out and purposely induce a negative life event.
