> I didn’t need comments if I wrote self-documenting code.

More than any other approach to coding (x-based-development etc), this has come up most frequently for me personally, and it astounds me how many people have this mentality.

Comments are a way to break out of whatever terse syntax your given language requires and speak directly to the developer. A single comment can house so much more context and insight the best-formatted code could ever hope for. When the only downside is some holier-than-thou idea of "I shouldn't be doing this" (despite the fact you clearly need to), I'm surprised so many people fall for this terrible mentality.
