1, everyone knows the useful use, but they don't know the useless use. The useless use is for the great use. -Zhuangzi
No matter what kind of knowledge you have, it is useful for your intelligence. It will throw away useless things and keep good things. -At most? Sparrows
3. Being useful means slavery. Useless means that you only exist for yourself, and uselessness is the real freedom. Because it is useless, it can be used for personal use. -Zhang
Things that taste good in the world, including poetry, wine, philosophy and love, are often useless. Singing useless poems, drinking useless wine and reading useless books sound useless, and finally become useless people, but live a very interesting life. -Zhou's leisure.
5. Reading some useless books, doing some useless things and spending some useless time are all in order to keep an opportunity to surpass yourself beyond all the known. Some great changes in life began from this moment. -Liang Wendao's "Music"
Second, the typical case:
1, Haizi is nothing, he is only obsessed with the beauty of "spring blossoms facing the sea", so he is pure and contains no impurities; Nalan is useless. He only looks for the mood when he first met the Iraqis, but everyone can sing water words. How many people know Nalan's mind? Li Yu is useless and his eyes are heavy. After the Southern Tang Dynasty, the country declined, but his writing is as beautiful as running water. It's useless, these useless people, what they present to us is useful.
2. Oak became a sacred tree because it was useless, and lived happily for centuries; Catalpa bungeana has become a ghost by the sword because of its usefulness, and it has been ruthlessly cut down year after year. This is the misfortune brought by usefulness and the luck brought by uselessness.
3. The knowledge in primary and secondary school textbooks is useless, but it helps us to expand our thinking and broaden our horizons; Mathematics is useless, but it stimulates the potential of the brain and makes people flexible; Confucius is useless, regardless of grain, but he is a Confucian master we admire; Zhuangzi is useless and inactive, but he is also happy. His views are still difficult to understand. From this point of view, useless people can be useful. All useless things are for accumulation and thin hair.
4. Van Gogh devoted all his passion to art, but only sold one painting; Balzac wrote day and night and ended up in poverty; Michelangelo has been carving and painting all his life, but he has only got countless pains ... However, it is their "useless" works that have opened one door after another and made a great splash in the history of human civilization.
Qian Xuesen has been engaged in scientific research all his life, but he is still grateful for the education he received in China since childhood. This "useless thing" has made his national integrity and perseverance; Einstein devoted his life to theoretical physics, but he still benefited from the violin he learned as a child. This "useless thing" has made his extraordinary creativity. Picasso devoted his life to the art palace, but he was still grateful for teaching himself physics knowledge. This "useless thing" has made his bizarre and exquisite painting art. No matter whether you are in busy study or intense work, you should spare some time, listen to famous lectures, learn practical technology, cultivate a hobby, participate in some practical activities, and then skillfully apply it to your own career to turn "useless" into "useful" and enrich yourself.
6. Jobs was obsessed with calligraphy when he was young, so he went to Reed University because Reed had the best calligraphy education in America. "I was obsessed with calligraphy at that time just because I liked it. I never thought about its practical application in life. I didn't expect to enter the IT industry ten years later and actually use what I learned in calligraphy courses. Ten years later, when I designed the first Apple computer, I applied' calligraphy' to font design. " As a result, with the world's first computer that can realize font typesetting, many people fell in love with Apple.
7. A deer came to the river to drink water. It looked down and saw its reflection in the river. The deer was satisfied with his two big, thick horns with beautiful branches, but he looked at his four legs and said, "It's just that my legs are not very nice, thin and weak." Suddenly, a lion jumped out of nowhere and pounced on the deer. The deer ran to a large clearing, and the lion was left behind. But as soon as it turned into the forest, its head was hooked on a branch and the lion caught it. Before dying, the deer said, "I'm such a fool!" " What I thought was ugliness and weakness saved me; And what I am proud of has ruined my life. "
8. Edison made 1200 experiments in order to find an efficient filament material when developing incandescent bulbs, but no satisfactory results were obtained. An ignorant person quipped, "You have failed 1200 times." "No," Edison retorted, "I proved that 1,200 materials are not suitable for filament, which is a great achievement." Great scientists use "useless" materials as irrefutable evidence to continue their experimental exploration.
9. Useful and useless, all from different angles. Only by analyzing things from multiple angles and levels can we get an objective and fair evaluation. "When you look at the mountains, the heights are different." If you look at mountains, why not look at people? Everyone hates villains, but Lao Tzu said, "People who are not good to others are the capital of good people." The bad guys are the reference of the good guys. Taking the bad guys as a mirror can make fewer mistakes and detours. So, what works and what doesn't? There is no certain standard. If it can be used, it will become useful, and if it is not used, it will become useless. It's the same for things and people.
