【正文】 屏住呼吸，生活停滯；呼出呼吸，更多新奇與經(jīng)歷又將拉開序幕。 Whenever a painful situation arises in your life, try to embrace it instead of running away or trying to mask the hurt. When the sadness strikes, take a deep breath and lean into it. When we run away from sadness that’s unfolding in our lives, it gets stronger and more real. We take an emotion that’s fleeting and make it a solid event, instead of something that passes through 中出現(xiàn)痛苦的事情時(shí)，別再逃跑或隱藏痛苦，試著擁抱它吧；當(dāng)悲傷來襲時(shí)，試著深呼吸，然后直面它。既然如此，何不嘗試打開心門，擁抱生活中的各種可能，讓世界感化我們呢？ Whenever we start to let our fears and seriousness get the best of us, we should take a step back and reevaluate our behavior.
