Does watching Guiguzi Sun Tzu's Art of War help to improve the ability to cope with the world?
It can make you learn more, but how much you improve depends on yourself. The ability to get along with others is a kind of understanding combined with one's own experience, just like I give a good cookbook to a person with a cooking background, who can make good dishes with a little study and understanding. But if you give it to someone who has never been in the kitchen, what can you expect him to understand?
