First of all, give the poster a hug.
The poster's problem is clear: he arranges a lot of study for himself every day. This shows that he is a person who demands progress, is very demanding of himself, and also hopes to improve. At the same time, it is evident that the poster is a person with an anxious personality. He arranges too much for himself every day but has difficulty implementing it.
In response to the poster's question about learning difficulties, I have the following suggestions: Read the book Cognitive Awakening. It mentions a method that is the most effective learning method, which is "by feeling." If the poster feels that the content they are learning now is too much and they cannot use it, then they should ask themselves, "What is the content I have learned so far? Why do I want to learn this knowledge?"
What can you use now? Prioritize these contents. Ask yourself: is this knowledge useful for my promotion and salary increase now? Are you more motivated to learn?
I highly recommend learning "by feeling," or the "fuse-free no-reading method." It's an effective approach. When you learn by feeling, you'll find that what you're learning is challenging, but you can find something that's attractive and not too difficult. This type of knowledge stimulates your thinking and makes you very thoughtful. It's the best way to improve your learning.
The second point is that the original poster said that he himself would be more fearful. In fact, I am a person who is prone to anxiety and fear in my ordinary life. I am always afraid that others will say that I am not good, and I have this kind of anxiety. Two days ago, I read an article on Zhihu called "All Psychological Problems Stem from Fear." The author of that article wrote very well, and I strongly suggest that the original poster read it on Zhihu because many people below also reflected that the article was particularly well written. Some people even said that after reading this article, I would be able to solve 90% of my psychological problems. Fear is like a spring: the stronger you are, the weaker it becomes.
The original poster needs to do two things: first, figure out what he should do; second, conquer his fear and ask himself why he is afraid. He needs to dig deep and ask himself more "why" questions, face his fears head-on, and slowly adjust this emotion. He can do it!

I can totally relate to feeling like you're not making the progress you hoped for despite putting in effort. It's frustrating when it feels like the more we learn, the more we realize how much we don't know. Sometimes scaling back and focusing on quality over quantity might help ease the anxiety.
It sounds really tough when your achievements feel invisible even to yourself. Maybe setting smaller, more manageable goals could help build up confidence and provide a sense of accomplishment. Over time, those small wins can add up to something big.
The pressure we put on ourselves can be overwhelming, especially with external voices like mocking classmates adding to the stress. Remembering that everyone has their own journey and pace might help silence some of those critical voices. Try being kinder to yourself.
Sometimes our pursuit of perfection becomes our biggest obstacle. It's okay to embrace imperfection and acknowledge that learning is a nonlinear process. Focusing on personal growth rather than comparison to others can lead to a more fulfilling experience.
When I face similar struggles, I find comfort in connecting with people who understand. Sharing worries with supportive friends or a mentor might offer new perspectives and remind you that you're not alone in this struggle.
