We all know our childhood is important, but we often ignore the importance of the ages from 20 to 30.
Actually, we make many important decisions in our life when we are 20 to 30 years old, such as choosing our first and second jobs and choosing our partner.
All these things are of great importance even for our entire life.
如果你开口说了，会发现我又猜到了很多吧嘿嘿

【因为这篇TED内容有点难，我基于上面的简单表达稍微优化一些，出一个介于上面和下面TED中间版本】
We are all aware that childhood plays a crucial role in our development. However, we frequently overlook the significance of the period between the ages of 20 and 30.
In fact, during our twenties, a large number of pivotal （至关重要的）decisions are made that shape the course（进程、轨迹） of our lives. These include not only selecting our initial （最初的）and subsequent（随后的） jobs, which lay the foundation for our careers, but also choosing the person with whom we might build a life together.
Each of these choices is very important. They can have a big and long-lasting effect on us. They don't just affect our near future, but also have an influence all through our whole lives.
We all know that childhood is a crucial period for the development of a person's brain and emotions. However, we often trivialize the decade that actually plays a decisive role in life, which is the decade from 20 to 30 years old.
我们都知道儿童时期是人大脑和情感发育的关键时期，却总轻视实际上对人生起决定性作用的十年，是20-30岁的这十年。
We know that 80 percent of life's most defining moments take place by age 35. That means that eight out of 10 of the decisions and experiences and "Aha!" moments that make your life what it is will have happened by your mid-30s.
我们知道，人生中 80% 具有决定性意义的时刻都发生在 35 岁之前。这意味着，让你的人生成为现在这个样子的十件事中，有八件决定、经历和 “顿悟时刻” 都会在你三十五六岁之前发生。
defining：/dɪˈfaɪnɪŋ/ 决定性的；起决定性作用的；明确的
take place 发生

二十多岁时大脑会再次发育，性格会产生非常大的变化。
We know that the brain caps off its second and last growth spurt in your 20s as it rewires itself for adulthood, which means that whatever it is you want to change about yourself, now is the time to change it. We know that personality changes more during your 20s than at any other time in life.
我们知道，大脑在你二十多岁时会完成第二次也是最后一次发育高峰，因为它在为成年期重新构建神经连接，这意味着，无论你想改变自己的哪方面，现在就是改变的时候。我们知道，人的性格在二十多岁时的变化比人生中任何其他时期都要大。
caps off：/ˈkæps ɒf/ 完成；结束（这里 “caps off its second and last growth spurt” 表示完成第二次也是最后一次发育高峰）
spurt：/spɜːt/ （增长、活动等的）突然爆发，猛增，这里指发育高峰
rewire：/ˌriːˈwaɪə(r)/ 给（建筑物等）重新布线；（这里指大脑）重新构建神经连接

职业生涯的前十年非常重要
And we also know that the first 10 years of a career have an exponential impact on how much money you're going to earn.
我们也知道职业生涯的前十年会对你未来的收入产生指数级的影响。
The partner you choose or the marriage you enter into when you're young often has a lifelong impact on you.
年轻时选择的伴侣或婚姻往往会影响你的一生。
