This is Hu Shi's famous saying, and the following is my personal understanding. 1, this sentence means: if you want to succeed, you must work hard; Hard work will certainly pay off, but this kind of success is not only a reward for yourself, but also a reward for others. Donated by Tang: failed, wasted, wasted. Literally, this word means "donate abruptly", that is, donate aimlessly, without money, or ask for money. Although there are a few successful people, most people may have enjoyed the benefits brought by successful people. For example, although printing, gunpowder and compass were not invented by foreigners, they did not prevent foreigners from using them; Electric lights, telephones, televisions, cars and computers were not invented in China, but they did not prevent China people from using them. In other words, success is not necessarily "me". Personally, success is success, and others think your success is success. There is another meaning. Your success does not necessarily bring benefits or the joy of success to the human body "I". The result of your efforts has brought benefits to others and is also a success. A leader or collective leader who is determined to serve the people and applies this concept to the people will make the whole people happy. Don't we also share the happiness of success from colleagues, classmates, comrades-in-arms and old friends, relatives and friends? If people strive for the same goal, then no matter who can achieve it, the universal meaning of the goal itself is the same. In this sense, success is not necessarily in me. So it is "I don't have to succeed". 3. No matter whether your efforts are good for others or yourself, if you want to succeed, you must work hard, and your efforts will definitely not fail, and there will definitely be a reward, although this reward may not only be for yourself, but also for others. In a word, your efforts will definitely pay off. ———— So "skills can't be donated."
