Everyone who has faced the need to learn a complex and unappealing text knows how difficult it is to force oneself to concentrate on it with a will. But the matter can be helped if you do not just read the text, but actively work with it: draw up a plan, take notes, build diagrams that reveal the connections between the events or processes described. It doesn’t matter what program you are going to work on, it’s important that it exists and is implemented point by point. Then the attention will be steady, and the work productive.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
