【正文】 些東西根本就可有可無；初中時(shí)，以為要有一場暗戀才意味著真正的成長，但三年過去后，自己心平氣和的寫同學(xué)錄的時(shí)候，突然就發(fā)現(xiàn)是不是真正的成長了，好像并沒有那么重要了；然后到了高中，覺得非要吐露出自己的心聲才能為高中生涯里的懵懂情愫劃上一個(gè)句點(diǎn)，但畢業(yè)晚會(huì)的時(shí)候最終還 是被梗塞在了咽喉，后來再次站在他曾經(jīng)揮汗如雨的球場，看著他投過籃球的球框時(shí)，突然間發(fā)現(xiàn)自己已經(jīng)想不起他的 容顏。 At the moment, the sky is dark, the air is fresh factor after just rained. Suddenly thought of blue plaid shirt。我們假裝一切仿佛都不曾發(fā)生，以此試圖忘卻傷痛，可就算隱藏得再好，最終也還是騙不了自己。 The initial impulse is to run away — to try and suppress these feelings by not acknowledging them. When we do this, we close ourselves off to the parts of our lives that we need to experience most. The next time you have this feeling of being truly unfortable, do yourself a favor and lean into the feeling. Act in spite of the fear. 我們的第一反應(yīng)總是逃避 —— 以為否認(rèn)不安情緒的存在就能萬事大吉，可這也恰好妨礙了我們經(jīng)歷最需要的生活體驗(yàn)。s not needed. Instead, he plans to deploy his 270squarefoot (25squaremeter) main chute at an altitude of around 5,000 feet (1,524 meters). In order to deploy this chute successfully, he will have to slow to 172 mph (277 kph). He will have a reserve parachute that will open automatically if he loses consciousness at mach speeds. Even if everything goes as planned, it won39。 2. Embrace the unfortable We all know what that twinge of anxiety feels like. We know how fear feels in our bodies: the tension in our necks, the tightness in our stomachs, etc. We can practice leaning into these feelings of disfort and let them show us where we need to ，也都感受過恐懼造成的生理反應(yīng)：脖子僵硬、胃酸翻騰。 Baumgartner the disappointing news: Mission aborted. r plays an important role in this mission. Starting at the ground, conditions have to be very calm winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our daytoday weather lives. It will climb higher than the tip of Mount Everest ( miles/ kilometers), drifting even higher than the cruising altitude of mercial airliners ( miles/ kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence. We often close ourselves off when traumatic events happen in our lives。嫌惡過自己的怯懦，最終卻發(fā)現(xiàn)有很多 緣分 ，有很多錯(cuò)過，好像冥冥之中真的已經(jīng)注定。 Then in high school, think don39。s plaint.
