I read this sentence intuitively, and it is correct. At that moment of intuition, what did I think? I got it. For example, you think you know something, but it's embarrassing to use it. In fact, this time will not bring you trouble.
How to avoid this trouble? I think it's also very simple, that is, when you think you know something, say it, teach it to others and make a course. In the process. You can know where you are. This is not a special meeting.
There is also the need to think more. If you think more about a skill you have learned, the more you write, which proves that the deeper you master, the deeper you understand.
Of course, the unknown won't bring us trouble, because we don't know at all. Although what we don't know is also affecting our lives, if we take me as the center and we don't know him naturally, he won't be natural, and we won't even consider this position. We won't feel that this position has brought trouble to our lives.
What about the known ones? As we all know, it's no trouble. When you have a clear understanding of the practice of a thing, although it is complicated, you won't feel trouble. What troubles you must be that you know a little but have no perspective. You don't understand thoroughly, but you know some steps, but you still don't understand clearly. This will bring you a lot of trouble and make you feel very troublesome.
