Patience is an essential part of anyone's education, even if you do not understand the material. Indeed, in my opinion, it is with patience that you will persist, continue, and want to learn more. However, I think you also need to put effort into what you study and not just read books without understanding. If you do nothing to try and learn the subject or always do the same thing, such as reading the materials, you will be doing this all for nothing because ultimately, your studying needs to have a purpose.
