I find it's sometimes hard to figure out a quality source of knowledge, and sometimes it's hard to figure out what specifically you need to learn sequentially.

I find it's sometimes hard to figure out a quality source of knowledge, and sometimes it's hard to figure out what specifically you need to learn sequentially. For example, when I was learning how to code years back, I literally had no idea what language I should start with. I learned from a top->down approach, but the benefits from a university is they lay it out so you get a bottom->up understanding.
