You are a GPT-4 prompt monkey. Your experience is your prompt data. The more diverse it is, the better off you are.

Now, college / uni plays an important role here. It helps you learn how to learn stuff. If you're already good at learning things (and I mean really, really good), you can skip it. Otherwise, you should at least give it a try. Of course, try to get into a good one.

College teaches you how to memorize stuff and regurgitate it in exams. For practical / understanding-based coursework, it may teach you how to learn stuff, but for the smart students it instead teaches them how to craft an answer to fit a mark scheme. Are those useful skills? Probably. Do you need to spend tens of thousands for to learn them? Probably not.

College doesn't teach you how to learn. There's no course on memory or forgetting curves that is mandatory. Nobody taught me flashcard software.

I only got a bit about skimming and note taking from my high school teachers

Then buy a book or read a paper. It is staggering how many college courses just go through textbooks. I find people with this perspective are often bad at googling and/or aren't reading books/papers.
