What books should I read in the third year of high school to adjust my mentality?

I think books like Caigen Tan and Night Talk Around the Furnace are just right for you to read.

You are in the third year of high school, so you should focus on your study. And the words about learning in "Night Talk Around the Furnace" are as follows:

Tales must be hidden, such as rough diamonds and jade, but Ri Zhang is also dark; There is no interruption in learning, such as flowing water and clouds, and the day goes on.

no matter how talented you are, you can study hard and ask questions, and you can think of a reason for everything, and you will have your own day of righteousness. I don't think my family background is poor, but I can be honest and mature, and I don't care what I do, so I am the person that the township party looks up to.

I think you will gain something by reading more.
