The phrase "at the beginning of life, human nature is good" can explain the cultivation of quality. Life is like a blank sheet of paper, and the surrounding living environment is the master who painted this blank sheet. So the master painter set the tone for this blank life.

Laozi also said that "moral cultivation" is the foundation of all things, and this "moral cultivation" is the cultivation of quality.

However, the greatest thing about us human beings is that "we are thinking creatures". It is because of thinking that we can sum up the logic suitable for our existence in the living environment and develop a unique and suitable three views. The performance of this three views is the quality of this person.

Of course, with the change of environment, a person's cognitive ability will also break at random. The three views will certainly be constantly revised. This process will last until the end of life. This is of course a long training process.
