1. They choose to have healthy relationships.
1. 拥有健康的恋爱关系。
I've learned to be picky over the years about whom I let into my inner circle of friends. Why? Because I believe close relationships are the key to sustaining happiness. One profound longitudinal study proves this. For 80 years, researchers followed 268 men who entered Harvard in the late 1930s through war, career, marriage and divorce, parenthood and grandparenthood, and old age.
多年来，我渐渐变得挑剔，不轻易让别人走进我的朋友圈。为什么？因为我认为亲密的恋爱关系是维持幸福感的关键。一项颇具意义的纵向研究证明了这一点。80多年来，研究员对268位男性进行了跟踪调查，他们在20世纪30年代初进入哈佛大学，历经战争、职业变化、结婚、离婚、荣升为父亲、外祖父、渐渐衰老。
Robert Waldinger, a professor of psychiatry at Harvard Medical School and the current director of the study, told the Harvard Gazette: "The surprising finding is that our relationships and how happy we are in our relationships has a powerful influence on our health. Taking care of your body is important, but tending to your relationships is a form of self-care too. That, I think, is the revelation."
哈佛大学医学院精神病学教授、本研究的现任主任罗伯特·沃尔丁格对《哈佛公报》（Harvard Gazette）说道："令人惊奇的是，我们的恋情以及在这段感情中我们是否开心对我们的健康有着极大的影响。照顾好自己的身体十分重要，但管理好自己的恋情也是一种自我照顾。我认为，这是一种启示。"
2. Have a mindset of giving.
2. 愿意给予。
The late Jim Rohn said, "Only by giving are you able to receive more than you already have." In the book The Go-Giver, the main character, Joe, learns that changing his focus from getting to giving--putting others' interests first and consistently adding value to their lives--ultimately leads to unexpected returns.
已故的吉姆·罗恩说道："只有给予，你才能获得比现在更多的东西。"在《给予的力量》（The Go-Giver）一书中，主人公乔学会了转变自己的注意力，从接受转变为给予--首先考虑他人的利益、不断为别人的生活创造价值--最终带来了意想不到的效果。
Now science confirms that giving makes us feel happy, is good for our health, and evokes gratitude. One Harvard Business School report even concluded that the emotional rewards are the greatest when our generosity is connected to others, like contributing to a cancer-stricken friend's GoFundMe Campaign.
现在科学证明：给予能让我们感到快乐、有利于我们的身体健康、让我们对他人心存感激。哈佛商学院的一份报告甚至总结道，为他人慷慨解囊的时候，比如为癌症朋友捐款，我们能得到最多的情感回报。
And before you restrict your giving to financial generosity to something or someone, consider the positive impact of giving of your time, mentoring others, supporting a cause, and fighting injustice.
限制自己为他人或他事提供经济支持前，请先考虑付出时间、指导他人、支持一份事业和反对不公平所带来的积极影响吧。
3. Practice mindfulness.
3. 练习正念。
Positive and happy people make the daily choice of surrendering their thoughts and feelings to the moment. By being mindful and focusing your awareness in the here and now, by calmly acknowledging and accepting your feelings and thoughts, you attain great peace and free yourself from worry.
快乐积极的人每天都会摒弃杂念、感受当下。此时此刻集中注意力，冷静地承认且接受自己的情感和想法，你就会获得莫大的平静、甩掉一切烦恼。
4. Have good emotional boundaries.
4. 懂得划分情感边界线。
Negativity is rampant. Happy people remain in the positive because they control what they let in -- whether on social media or in people interactions.
负面情绪十分猖狂。快乐的人会保持正能量，因为在玩社交媒体或与他人接触的过程中，他们会控制自己不受负面情绪的影响。
