My friend, I must tell you that you can't learn marketing. For example, you can learn to imitate entrepreneurs, but you must always be slightly innovative. I feel it necessary to tell you this.

All marketing video teaching on the Internet is just money, because it is very simple to take out a book now, just copy it.

Secondly, you don't know the roots of these teachers at all, and you don't know what they are.

Besides, marketing requires thinking, vision and a grasp of the situation, and it can't be learned simply by a set of tutorials, at least that's my understanding.
