- How is your brain doing?

Just like in twenty years! I do not notice any difference either in terms of susceptibility to delusions, or in terms of its capacity. Tomorrow, for example, I'm flying to a medical convention.

- However, there must be some limit to the capabilities of the brain, laid down genetically?

No. My brain will soon be a hundred years old, but it does not know decrepitude. My body is shrinking - this cannot be avoided. But the brain is not!

- How do you do it?

The human brain has tremendous neuroplasticity. While some neurons die, others reorganize and carry on with their functions. But for this they need to be encouraged.

- But how?!

Keep your brain engaged and active, make it function, and it will never degrade.

How to use the book

Our reader should realize the great importance of the training of memory and cognitive abilities. This book is a guide for those who wish to know the weaknesses of their memory and learn strategies and techniques to improve its performance.

The author did not try to write a scientific work on memory and does not offer a specific exercise program. Memorization techniques are presented in a playful way, since, according to the author, this is the most effective and natural way to train memory. Play, challenge, competition - that's what motivates us at any age. It is important to understand: a person learns only what seems important, interesting and motivating to him, and forgets everything else.

Difficulty levels

Exercises are divided into levels: easy, medium, difficult and very difficult. Although it is not an easy task to create a classification, the reader should keep in mind that it represents only a private opinion.

In addition, do not forget that intelligence is characterized from different sides and there are different types of intelligence. In other words, what may be easy for one person may be very difficult for another.

Operating procedure

The level of difficulty indicated in each exercise will allow the reader to create their own memory training plan. You can do the exercises in the suggested order or move from easier to more difficult. Any sequence will be correct. The main thing is not to give up classes. Progress and improvement come for everyone in due time, as they depend on the inner rhythm of a person.

Tips

Most of the exercises contain advice referring to memory techniques or methods that make it easier for the reader to solve the problem. In addition, they will allow you to better master the memory strategies from the theoretical part of the book, since they can be applied in everyday life.

memory notebook

It is better not to write or make notes in the book. It is recommended that you keep a notebook, which you can call a "memory notebook" if you wish. In it, you can record the results of the exercises and monitor your progress, or keep a record of the mnemonic methods used in each exercise and make notes about what type of memory you think was activated when you performed it. Evaluate work based on the following questions:

Did you spend more or less than the recommended time on the exercise?

How many objects were remembered and how many of them were remembered correctly?

What difficulties arose during the exercise?

How many repetitions did it take to memorize?

Consider also any other criteria you see fit.

Answers to the exercises

You will find answers to most of the exercises at the end of the book. However, some need to be checked immediately after the solution, by re-reading the task or referring to the picture. It is not recommended to look at the answers at the first doubt.

Do not give up! Perseverance, perseverance, patience and willpower are the four most important qualities that stimulate our brain. Solving a problem brings great satisfaction. While doing a seemingly incomprehensible game or an intelligence exercise, you will find that the task contains a huge amount of information in a compressed form, which will be revealed to you immediately after the solution. At this very moment, you will feel free from restrictions, feel uplifted and in an instant move from awareness of your own clumsiness to virtuoso mastery of mental techniques. This feeling, besides being very pleasant, is extremely stimulating to the brain.

• Read the assignment carefully, carefully concentrating on all the details.
• Don't rush into the task. Make sure you understand what needs to be done.
• If you understand the task, try to find among the past events of your life a similar experience that will help you solve the problem.
• Each exercise is a challenge, so your mental attitude is very important.
• If at first you don't succeed, don't lose heart. Don't quit the exercise. Perseverance, perseverance and patience are very useful qualities for solving any problem. The perfect effort will reveal your strengths and make you believe in your abilities, including the ability to work long and productively.
• Think of difficulty as a great opportunity to learn something. Remember: the huge path done to achieve the result is much more important than the result itself.
• At the end of the book you will find answers to the exercises. Check with them after you complete the task.

Forward! Drop doubts and make your memory work!
