One day is divided into "three days"

Obruchev, a famous Russian geologist, divides every working day into three days: the first day is from morning to two o'clock in the afternoon to do the most important work; "The next day" from two o'clock in the afternoon to six o'clock in the evening, do more relaxed work; The "third day" is from 6 pm to 12 pm, which is mainly used for reading or necessary activities. He said that this is equivalent to doubling life.

The conversation is only five minutes.

Deng Zhongxia, a revolutionary martyr, cherished his time studying in Peking University. At that time, people often came to Deng Zhongxia to talk nonsense. Finally, he wrote a "five-minute talk" note and posted it on the table as a reminder. As a result, he not only won valuable time by himself, but also educated people who like to chat.
