And yet, if you proceed as if it were correct, you'll be amazed at what you'll accomplish. The comment I was replying to was essentially asking, "What would've helped you back when you were in my position?" Ten out of ten times, I'd choose to tell myself, "Stop trying to read about how graphics engines work. Figure out how to get triangles up on the screen, without copying someone else."

The best I can say is that my career began from that method. And by asking a lot of questions on IRC.

Glad it worked for you, but that doesn't make it good advice. And doesn't change the lack of uniqueness. It's usually a mistake to generalize from your own experience, when thinking about pedagogy. I'd wager that most people would do ok following that advice as if it were true ... But not as well as if they'd read as well.
