What is this short essay about? Mainly about goals and motives. I agree, this is not the most meaningful answer, but a long explanatory note is of no use here, since everything stated below is certainly familiar to you in one form or another. My main task is only to serve as a reminder, to awaken in memory that which is close and familiar, which, however, is quickly forgotten. I am sure that as you read, you will repeatedly think: “This is familiar to me,” “I knew all this,” which means the goal has been achieved. Remembering even such a minimum is not an easy task, because a person, having heard something familiar, stops delving into the essence (a weakness that is difficult to cope with), and the principle “repetition is the mother of learning” no longer works. By the way, many famous sayings will be presented below. Thus, your humble servant tried to bring the work to a thesis form. The examples you encounter will most likely be quickly forgotten, and the words of famous personalities will certainly take their rightful place in your memory. Especially if my opinion does not differ from their views. Don't be surprised, most of the examples here will be related to childhood. I have no illusions about the fundamental differences in the childhood of my compatriots, whether twenty or fifty years ago. Everyone experiences the same feelings and goes through trials, gaining the most valuable experience. It is by relying on it that one can acquire what is called worldly wisdom, not limited only to the sphere of professional activity. Therefore, I did not find anything shameful in references to childhood, citing simple, but most important phrases or examples of past years. I am grateful to you, dear Reader, for your time. I sincerely hope that this text will be interesting and useful to you.
