> good commenting skills take years to master

As a newer developer, it’s nice to hear you say that. I often find that I spend more time deliberating over comment wording and variable names than I spend writing the code itself!

You are on the right path! Most new devs don't even comment at all (and plenty of senior devs). As for variables names, I wouldn't fret about that. Yes, 'foo' isn't a good var name but the exact name doesn't matter as much as one would think.
