There is such a cool thing - a Venn diagram. I recently advised a friend to use one and was so inspired that I used it on myself. And then I decided to write to you about it. In general, it helps to visualize the relationships of different categories with each other. These things can be very complex, but I think they are well suited when we need to visualize the relationships of three factors. Two is too little (you can do it in your head), and more than three - you have to bother too much.
An example is in the picture. By the way, I couldn't come up with a solution that would satisfy all three requests in my example. So this psychotherapeutic method is apparently not all-powerful. We'll keep looking.
