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 us. 當(dāng)生活中出現(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. The items listed below are six ways you can open your heart more fully and pletely. 當(dāng)恐懼與焦慮來襲時(shí),我們應(yīng)該退后一步,重新反思自己的言行。 instead of letting the world soften us, we let it drive us deeper into ourselves. We try to deflect the hurt and pain by pretending it doesn’t exist, but although we can try this all we want, in the end, we can’t hide from ourselves. We need to learn to open our hearts to the potentials of life and let the world soften us. 生活發(fā)生不幸時(shí),我們常常會(huì)關(guān)上心門;世界不僅沒能慰藉我們,反倒使我們更加消沉。突然想到那件藍(lán)格子襯衫;那些被折成各種各樣形狀的信紙;那段從街角深巷伊始的友誼;還有那場還沒有開始就宣告了終結(jié)的邂逅計(jì)劃 …… 那些年那些天的非做不可,終于和青春一樣,都將在我們的人生中謝幕。 Have declared the end of the encounter that haven39。 Those were broken into various shapes of stationery。那些曾經(jīng)所謂的非做不可,只是青蔥年華里自己給自己注射的一支強(qiáng)心劑,或者說,是自以為是的精神寄托罷了。也曾經(jīng)好像已經(jīng)下定了決心去做某件事,但更多的時(shí)候是最后又打起了退堂鼓。s time, your ideas are always special to clear.

Dislike his cowardice, finally found that there are a lot of love, there are a lot of miss, like shadow really have been doomed. Those who do, just green years oneself give oneself an arm injection, or is a selfrighteous spiritual. 一個(gè)人的時(shí)候,自己的想法總是特別地清晰。Originally, this world, can produce a chemical reaction to an event, in addition to resolutely, have to do, and 來,這個(gè)世界上,對某個(gè)事件能產(chǎn)生化學(xué)反應(yīng)的,除了 非做不可的堅(jiān)決,還有,時(shí)間。t want to give vent to out your inner voice can be in the high school children of the feelings in a period, but was eventually infarction when graduation party in the throat, later again stood on the pitch he has sweat profusely, looked at his thrown a basketball hoops, suddenly found himself has already can39。t really grow up, it seems is not so important。 The end of our life, and can meet many things really do? 而窮盡我們的一生,又能遇到多少事情是真正地非做不可?
