Therefore, to form a good habit, we must master this rule, that is, constantly hinting at ourselves and repeating suggestions. When people read a book, they often only read the important content once or twice. Have you asked them if they have read it? They say yes, but the important knowledge has not been implanted in your mind and will soon be blurred. The knowledge absorbed in this way can only be regarded as understanding and knowing, but it is difficult to do so. Only talk on paper, not actually use it. Only those who keep repeating correct beliefs can strengthen the positive beliefs in the subconscious and finally succeed.
