In an age of constantly evolving science and technology, we inherit lessons from those studies. Natural theology is something that every person should practice and promote every day. Self-study spirit will help us to improve ourselves more and more. What is self-study? Self-study is self-study, self-discovery, self-exploitation of knowledge by what you see and hear. Self-study is a spirit worth learning, admiring and promoting. Each person has a child, since birth, not everything is known, everything is information, it is necessary to have a search process to be able to find what you want. This thing will help for the basic body doesn't have more things that but open gain knowledge, train yourself to develop more and more. The things that we seek for ourselves will be remembered longer, understand more deeply what others perceive. Those who say they don't know, must learn, must ask. Thus, the copy does not know but refuses to seek and learn, only to be conveyed by others. That's really romantic. However, the learning style of many students currently does not bring good results because they do not regularly practice and cultivate the spirit of self-study. Students only rely on lectures in only 45 minutes in class without going to learn and explore outside. It is because of the teacher's attribute that students always fall into a state of not knowing how to deal with open-guided articles. She must be the one to train the children to learn calculus. She should not magic the lecture but should teach in an open way so that the children can follow it and find more. This is also an problem is a problem of the background education from the house is too used to the book of education. And result is the things that you must get. The status of rote learning, vegetarian learning, and cabinet learning also appeared from there. The students knowledge gaps many people do not seek, explore. Relying on too many references, sample texts, and sample documents with answers will spoil you. It is because the student is lazy to think and study, so he falls into a state. This is a matter of concern. This fact has once again defined the self-study spirit as extremely important, requiring regular practice and application. When we can build a habit of self-study, we will be shaped into a new way of thinking, independent of anyone, any document. Ho Chi Minh is a shining example for the spirit of self-study that each of us needs to learn and follow. Uncle went with empty hands, did many jobs to earn a living, taught himself foreign languages ​​to communicate. Uncle did not have money, but he was eager to learn, curious, so his success was understandable. If we don't learn by ourselves, we will be left behind, because there is no path to anyone, only we do not know the way out. Consequences of relying on such importance. Each person, each citizen needs to daily practice the spirit of self-study to improve themselves.
