Because there are some people for whom-no one is exactly or very few people are exactly 24 hours rhythms.
因为有人 基本上没有人的周期是正好24小时的
We are usually either somewhere between 23 and 25.
大多数人都是23到25小时之间
So for people whose circadian rhythm is 23 hours, they get very tired at night.
对于周期是23小时的人来说 他们到了晚上就会非常疲劳
But then they wake up very fresh in the morning.
但是他们早上却会精神抖擞地起来
Or people who are closer to 25 need that extra sleep in the morning.
那些周期是25小时的人 早上需要多睡一会
And it's for those people that I have this class at 11:30.
就是因为那些人我才将这课调到11点半
I know it's early but thank you for making the effort.
我知道是很早但是感谢你们的到来
When I got to college, most students were studying late at night.
我上大学的时候 大多数人都学到很晚
My roommates were studying late at night, starting at about 10 and going to you know midnight or 2 am in the morning.
我的室友就学到很晚 从晚上10点开始然后学到12点甚至凌晨2点
And that's when they are most productive. I wasn't.
这才是他们最有效率的时候 可我不是
And I would get up in the morning and I was tired, exhausted, couldn't really focus at night.
我宁愿早上早点起来 我在晚上会很累 根本无法集中精神
And when I heard about this productive hour, I changed my day. And I went to sleep early.
我听说了这样的效率时段后 我改变了作息 我早早睡觉
So when my roommates started to study, I actually went to bed,
在我的室友开始学习的时候 我上床睡觉
and got up really early when my roommates were still asleep and got my work done
然后在我的室友还在睡的时候起床
early in the morning, and then went to my 11 am class after I got my work done.
然后在早上早早地把工作完成 做完以后去上11点的课
And in 3 hours in the morning, I got much more done-more productive, more creative,
在早上的那3个小时内我完成了更多东西 更有效率更有创造性
much better retention than I did late at the night. These two things as I mentioned earlier
比我在晚上熬夜有效率得多了 我刚才说到的那两样东西
really changed my experience here-getting so much more in far less time.
真的改变了我在这里的经历 在更短的时间内学到更多
Not the perfectionist approach, the pursuing excellence approach.
不是完美主义的方式 是追求卓越的方式
