, in my mind constantly. Always feel oneself should go to do something, or write something. Twenty years of life trajectory deeply shallow, suddenly feel something, do 年齡已經(jīng)到了尾 聲。 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? During my childhood, think lucky money and new clothes are necessary for New Year, but as the advance of the age, will be more and more found that those things are optional。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。既然如此,何不嘗試打開(kāi)心門(mén),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 ,我們應(yīng)該退后一步,重新反思自己的言行。屏住呼吸,生活停滯;呼出呼吸,更多新奇與經(jīng)歷又將拉開(kāi)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 ,別再逃跑或隱藏痛苦,試著擁抱它吧;當(dāng)悲傷來(lái)襲時(shí),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 ,我們常常會(huì)關(guān)上心門(mén);世界不僅沒(méi)能慰藉我們,反倒使我們更加消沉。t really grow up, it seems is not so important??傆X(jué)得自己似乎 應(yīng)該去做點(diǎn)什么,或者寫(xiě)點(diǎn)什么。s actions.

However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept i. If you are worried about how the time limits apply to you If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement.
