Reading code of nice, successful, projects helps learn what good looks like, how the projects are structured, how each module minds its own business, etc. I'm not saying the code is perfect, but the improvement is faster than to do it in a vacuum. Writing the tutorial and documentation for a library and show it around to colleagues before you write the code has been helpful. "Would this make sense to you?" I also used to give non coders a laptop and the documentation for a library I wrote and tell them to follow the documentation to do something.
