First, pay attention and never take medicine. Many people think that their inattention may be due to some physical problems. In addition, there are all kinds of messy health care drugs circulating on the Internet, and propagandists can improve their memory. And those people ate the so-called IQ tax and bought these drugs to improve their memory, only to find that they were useless and even ate their bodies to death. In fact, if you want to improve your memory, it is mainly a way of thinking. It's no use taking medicine. You still have to exercise.
Second, concentrate and don't change the environment. First of all, memories are scattered, mainly because everyone's life is too fast now, and there is no way to calm down for some things. If you focus on a certain point, and don't rush to complete it step by step, only focus on it for 8 seconds, then you will find that memory can really stay in your mind for a long time. And don't change the learning environment at will, because when you enter a new environment, the memories in your mind will be re-matched, and then what you recorded before will be forgotten. Whenever I feel that I can't remember things, I can also clench my fist like this to extract information from my brain, which can also make people start to remember.
Third, sleep more and think more. Some people feel that it is impossible to cram knowledge into their minds. This practice of constantly instilling these things into their minds is equivalent to wasting time. It's better to go to bed and let your mind go empty. When you think about it after a while, you will find that some useless information will be removed.
