You can learn from others, but at your age, you can ignore hundreds of surnames first. Three-character classics and thousands of characters are very important, as well as juvenile Pai Qionglin. Of course, if you want to study something useful to your life, not just academics. That's the Analects of Confucius. Mencius, Laozi and Zhuangzi are all acceptable. Don't enter the Book of Changes yet. First, you must have a certain foundation of Chinese studies. I think The Analects is very suitable, but it may seem a bit boring now. There are more complicated dialectics in Laozi.
Mencius is better, and Zhuangzi is better, but without life experience and Confucianism as the basis, Zhuangzi would easily get lost, thinking that Zhuangzi was passive, and he saw through the world of mortals, so he followed Zhuangzi to become a hermit. Of course, it is ok to have a look.
To tell the truth, all of them can be involved. You are not young, and you know a little about Chinese. Besides, you can also understand the general Confucian classics (except Zhuangzi, of course).
If you really can't stand reading ancient Chinese, you can go and see what people in Lecture Room say. For example, Yu Dan said that she values individuals more. Don't go to see Yi Zhongtian, what he said is academic.
