Everything that is successful has its inherent truth, and successful people also have their own swords for success. The ancients said: "Take history as a mirror, you can know the rise and fall; With copper as a mirror, you can be well dressed; You can know right from wrong by looking at people as a mirror. "Every time we do something, we must have a reference, try to take fewer detours, or even take no detours. Learning from the past is the key to our success. But only knowing your own experience as a reference is a bit narrow, which is tantamount to sitting on a well and watching the sky. Wise men at all times and in all countries have always been good at learning from history and others.
Newton once said, "I see farther than others because I stand on the shoulders of giants." If people can learn to find their own direction from the feet of former people, they will certainly become a very great person.
Carnegie is very successful in "learning from others". Carnegie summed up the most incisive sentence on the road to success, which is similar to our sentence: "Fools only learn lessons and wisdom from their own experience, while wise people know how to learn and use other people's experience."
