與其一味顧慮重重,不如從局外人的角度看待 決策之事。其實,我們有能力面對這些痛苦的 感受,從中領(lǐng)悟到出路。 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 us. 當(dāng)生活中出現(xiàn)痛苦的事情時,別再逃跑或隱藏痛苦,試著擁抱它吧;當(dāng)悲傷來襲時,試著深呼吸,然后直面它。 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,我們常常會關(guān)上心門;世界不僅沒能慰藉我們,反倒使我們更加消沉。 Have declared the end of the encounter that haven39。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心劑,或者說,是自以為是的精神寄托罷了。s time, your ideas are always special to clear.

Always feel oneself should go to do something, or write something.
