@induktio Just let it flow; and don't question the choices TeX/LaTeX make until you're experienced and can do judgments. Among the worst errors one can make, there's trying to customize the output like it can be done with word processors. The motto is: if something is difficult to do with TeX, there are good chances it's typographically disputable.
@induktio Please, also tell you always wanted to chat with @DavidCarlisle, or he'll get offended.
@egreg Mostly, I am curious as to how best to devote my time to become more proficient in TeX and LaTeX. I definitely have the passion and the willingness. That is certainly not the issue. Mostly, I've just thought reading Knuth would be the best idea. But are there any books (in English because I'm not multilingual unfortunately) that you would consider very outstanding that are not part of what I have already mentioned I have?
