Upvoted for careful scholarship and a useful addendum (I'm OP)!
I sometimes wonder whether a lot of Knuth's greatness comes from doing more of the stuff everyone knows they should do but don't. If you read this interview (https://github.com/kragen/knuth-interview-2006) with Knuth, he talks about how he was nervous he wouldn't be able to learn calculus so just decided to do all the problems instead of just the assigned ones. Unsurprisingly, partly because he's Knuth and we all know Knuth can do math, he ends up really good at calculus:
> But Thomas’s Calculus would have the text, then would have problems, and our teacher would assign, say, the even numbered problems, or something like that. I would also do the odd numbered problems. In the back of Thomas’s book he had supplementary problems, the teacher didn’t assign the supplementary problems; I worked the supplementary problems. I was, you know, I was scared I wouldn’t learn calculus, so I worked hard on it, and it turned out that of course it took me longer to solve all these problems than the kids who were only working on what was assigned, at first. But after a year, I could do all of those problems in the same time as my classmates were doing the assigned problems, and after that I could just coast in mathematics, because I’d learned how to solve problems. So it was good that I was scared, in a way that I, you know, that made me start strong, and then I could coast afterwards, rather than always climbing and being on a lower part of the learning curve.
Yes exactly. It's always inspiring to see how (in his case) you just start doing things simply and methodically with focus, and eventually you get very far and become better than anyone else.
