That&#x27;s too rational. You need to have all the notes and stuff as well. You need to learn and expand your knowledge before you can go into practicing something. Even though I agree that I&#x27;ll never look at my old university-notes again, they did serve a very real and important purpose in the proces towards teaching me how to build something. Reflecting upon what you&#x27;re going to build, holding meetings and taking notes are important processes in mastering something. Even though it might seem a bit dull or not worthwhile compared to building stuff.
