What’s learnt from the textbook, stories are not real knowledge. After learning from the textbook and stories, you have to practice it and get your first hand experience for at least once, then you get some real knowledge.
After all, the purpose of learning knowledge is to use it. Only after you have used it, do you get it.
Real knowledge is not just words. Real knowledge is recorded by words, feelings, instinct and every single cell of your body.
