The concept of hedgehog comes from the ancient Greek fable The Hedgehog and the Fox, which tells that the fox is a cunning animal, and it can design countless complicated strategies to secretly attack the hedgehog. But every time the hedgehog curls into a ball, its spikes point in all directions. The fox is quick, smooth-skinned, quick-footed and cunning, and looks sure to win. Hedgehogs, on the other hand, are unremarkable, genetically like a hybrid of porcupine and armadillo. It walks around all day looking for food and taking care of its home. Although the fox is cleverer than the hedgehog, it is actually the hedgehog who wins every battle. This fable shows that the fox knows many things, but the hedgehog knows the most important thing, which is enough to make it escape from the cunning fox. In fact, people can also be divided into two basic types: foxes and hedgehogs. Isaiah berlin was inspired by this fable. He thinks that foxes' thinking is "disordered or scattered, and developed at many levels", and they have never concentrated their thoughts into a universal theory or unified point of view. Hedgehog simplifies the complex world into a single organized viewpoint, basic principle or basic idea, which plays a command and guidance role. No matter how complicated the world is, hedgehog will compress all challenges and dilemmas into a simple "hedgehog idea". The concept of hedgehog emphasizes that the essence of profound thought is simplicity. That's why those outstanding people are different from those who are equally smart. Darwin's natural selection: natural selection, survival of the fittest; Marx and materialism: Great Harmony; Einstein's theory of relativity: e = MC 2; Adam Smith and Division of Labor: "The Invisible Hand". It is these hedgehog-like people who simplify complicated events and bring us closer to ourselves. Based on the investigation of companies that have successfully leapfrogged from excellence to excellence, Jim Collins put forward the concept of three rings according to the concept of hedgehog-he found that the core competitiveness of every company trying to leapfrog is not piled up by random and simple concepts, but a profound understanding of the intersection of the following three rings: where can you be the best in the world, what drives your economic engine and what you are passionate about. In fact, it is also meaningful to apply the concept of "Three Rings" put forward by Jim Collins to personal self-pursuit, such as life goals and career choices. Take the application of three-ring concept in career choice as an example. When you choose a career, have you considered these three links: Is the career I want to pursue the most talented? I can make outstanding achievements in this profession, which is your core competitiveness. Sometimes the best you can do may not be what you are doing now. So you should pay attention to your insight into yourself. What drives your economic engine? You should not only have keen insight, but also be able to benefit from your excellent career to support your life and family, as well as your future promotion in your career. Are you full of enthusiasm? Can this job arouse your enthusiasm and go all out? The problem here is not to inspire enthusiasm, but to find out what makes you enthusiastic. There is a western proverb: "Shoemaker, just do your job." Walgreen Company is an excellent company, relying on the simple hedgehog concept: "The best and most convenient pharmacy will give customers considerable profits", and through persistent implementation, it finally achieved a successful leap. If you learn to find out the concept of hedgehog in your life and career, then focus on it and persevere. You are destined to be an outstanding person-live the life you expect and have the career you love. Isn't that your dream? Hedgehog concept tells us: focus on your core competitiveness, rather than easily distract your energy and resources.
