How to improve your life

如何让生活更美好

Get enough sleep

充足的睡眠

You can't cheat yourself on sleep and not have it affect you. Being tired actually makes it harder to be happy. Lack of sleep =more likely to get sick. "Sleeping on it" does improve decision making. Lack of sleep can make you more likely to behave unethically. There is such a thing as beauty sleep.

想要在睡眠上偷工减料又不受影响是不可能的。疲惫的时候是很难开心起来的，缺乏睡眠还容易生病。“睡一觉，明天再考虑吧”的确是有利于做决策的。缺乏睡眠的时候更容易做出毁三观的事情。还有美容觉的说法呢。

Naps are great too. Naps increase alertness and performance on the job, enhance learning ability and purge negative emotions while enhancing positive ones.

打个盹儿也不错。打个盹儿工作的时候反应更快，表现更好，学习更轻松，清除消极情绪，变得乐观积极。
