I suddenly felt that the text I had read recently was too simple and easy to understand, and I wanted to read some deeper content, but I had not yet found a breakthrough.
I once read some words about the level, saying that it is: change always has to retreat from the skin, change is not easy, it takes courage, it needs execution.
Just thinking that change is a layer is one layer deeper than not thinking that you need to change. And putting it into action to change is another layer deeper, a deeper level than just thinking about the need to change the idea.
Going back to the original starting point is not yet realizing that you need to change, which is called the first level.
Thankfully, I've crossed the first and second levels. Now that I am at the third level, all I need to do now is put the thoughts in my head into action and complete the leap from the third to the fourth level.
Here I have a careful wish, I hope that through my own efforts can successfully achieve change, like a better direction change, become a better self.
The above levels are only my understanding and cannot be studied.
