One of the many things that people don't tell you that you learn in college, is how to decide what work you have to do and what work you don't have to do. This is because many, if not all, teachers assign busy work. They don't do it on purpose all of the time, but you just don't need to do all of this work in order to learn the material.
Half of the stuff teachers present in their class is complete bullshit. It's an illusion of learning that the teachers force upon us in order to teach us one thing: to sort through bullshit. This is one of the most reliable bits of knowledge you will learn throughout your life.
This skill allows you to gather information from previously unreliable sources. It allows you to learn things where knowledge was previously unavailable. As long as you can differentiate between the reliable and the unreliable, there are no limits as to how far you can go.
