Were you the same when you were a junior? I was. I didn't have the experience to understand the impact of my changes. The norm reply on HN: "You need more mentoring or code review.". Sometimes (usually?) that is in short supply.

Absolutely. I made all the usual mistakes, and had to be mentored and learn from more experienced programmers.

(Alas! Sometimes you pick up bad habits from experienced people, and being a junior, you don't know better)

You raise a great point in your reply. At some point, as a junior, you begin to develop your own personal software philosophy and break-away from your seniors/mentors.
