Great article. Related to the “code quality” point, what I have personally realized is that it’s easy to over complicate solutions. Often, a simple solution is better (especially when it is part of a larger, more complex system).

When I was younger, I liked clever solutions to show off my skills. Now I cringe at that. Other people have to read my code. And more importantly, “I” have to read my code tomorrow or next week. I’ve started to really prioritize simplicity. Which is ironically quite hard!
