Textbook-like definition is: an interesting soul is a person whose information density and knowledge level are much higher than yours, who is willing to condescend to listen to your nonsense without nutrition, put forward some opinions you have never heard before, and subvert your short-sighted imagination and three views.
The easy-to-understand definition is that an interesting soul is a person with a high cognitive system, advanced thinking mode and a large amount of information and knowledge reserves. He is backward compatible, and with his unique humorous expression, he can grasp the main points more accurately than you, but you can't express them. He can express them with clearer logic and density. He can express your thoughts and even your subconscious. He is willing to listen to you sincerely and patiently. Although your content is childish and low-level, he is willing to focus on you and talk to him, which is like a spiritual massage. Wow, you will find this person so interesting!
So how to practice?
1. Read more books, practice more, answer more questions and think more: reading can improve your cognitive system and thinking mode, increase your information and knowledge reserve, practice more, gain real experience, hone your soul, temper a resilient soul, answer more questions and think more, and produce unique insights and wisdom;
Second, reach out to people with higher ability than you, and learn and improve in all directions;
Third, always keep a curiosity, always keep innocence and cultivate your own humor;
Fourth, when your cognitive system, thinking mode, information and knowledge reserves are higher than those around you, you should learn to be modest and learn to be sincere and backward compatible;
Finally, everyone is unique in this world. Don't frame yourself by other people's standards. I am who I am. Different fireworks, let's have a happy and interesting day!
