More trust, less questioning. Since you choose to follow your teacher, you should trust him! Unless your teacher is particularly bad, making continuous mistakes, and making multiple mistakes in a row or more, it is destined that they will not be a good teacher. If one person makes three mistakes and does not know how to change their own strategy, then I can only say that this teacher's popularity has not yet reached! But if your teacher's thinking is not a big problem, please trust him, after all, you are standing together with a common goal, all for the sake of making money!
