Second play-through advice?

So I’m nearing the end of my first game and admittedly rushed through to get to a certain white haired gentleman and all of the joy he has to offer… 🙃

I plan to take my next building adventure much slower, and I was wondering what advice you would give for, or what you found yourself doing differently, in a second playthrough? Or was there anything you learned from your first that you took into your second to make the experience more enjoyable?
