It is believed that intelligence is something given from birth. It cannot be improved. This is an erroneous point of view. Often people do not use and do not develop even a tenth of the intellectual capabilities that are given to them by nature. Bad memory, for example, can only be the result of the fact that a person leads the wrong way of life, or, corny, he rarely has to remember something. Imagination, attention, memory - all these components of intelligence need constant "pumping". The same rules apply here as in sports - the more and more regularly a person trains, the better the result.
There are many methods for the development of intelligence and its individual components. Many of them promise fantastic results in a very short time. But everything is not so simple, just as you cannot become a strong man in a couple of weeks, and you cannot become an intellectual in a couple of weeks. So, it's better to be patient and trust the old proven methods.
Reading of books
The main way to improve your intellectual abilities is to read books. They develop attention, memory and, of course, imagination. When watching movies, your brain assimilates ready-made images; when reading a book, you create them yourself. Therefore, a book should always be preferred over a movie. One of the features of our time is the predominance of clip thinking. This type of thinking has both its advantages (the ability to quickly switch attention) and disadvantages (inability to concentrate on one subject for a long time, superficial thinking). To overcome these shortcomings, you need to read fiction regularly. You can start with small stories, gradually moving on to more voluminous works. It is important not to skip pages and read the book to the end.
Studying of foreign language
It is very difficult for those with poor memory to learn foreign languages, but nothing develops memory like learning foreign languages. The main thing here is the regularity of classes and perseverance. At the beginning of the study, the results are practically invisible, and you need to show a fair amount of perseverance, repeating the same words over and over again. It would seem that perfectly learned material often disappears from memory after a couple of days. The method of learning foreign languages takes a lot of time, but gives good results.
Memorizing poems and quotes
An alternative way of developing memory can be memorizing poetry. You need to start with small and light poems, increasing the load over time. Memorizing quotes is more challenging. In addition to memory, memorizing poetry and quotes helps develop attention.
Meditation
It is difficult to overestimate the positive effects of meditation on intelligence. It's no secret that an overabundance of stressful situations negatively affects the functioning of the brain. With the help of meditation, you can release tension and distance yourself from endless problems that prevent you from concentrating on the current task.
Logic games, crosswords, etc
Puzzles, riddles and logic problems are very helpful in developing thinking. Tackling these tasks on a regular basis has a strong positive effect on brain function. You can start with easy children's puzzles, and gradually move on to more difficult ones. The brain necessarily needs difficult tasks, because only they contribute to its development. Doing (or better, composing) crosswords or Sudoku can also be helpful.
