A few of the lessons he talked about I've seen repeated on Casey Muratori's "Handmade Hero" series. Specifically point #3, he talked early on about writing simple code that fulfills one metric: it works. Afterwards you can see the implicit parts that should be made into functions, remove code duplication, and clean things up. However having that "full view" of a chunk of code makes the process easier. Also point #4, he writes an interactive write-compile-test system using an executable hooking into a shared library which contains all of your code. That way you can compile and see the results quickly on a still running executable of your game. Very fast feedback without having to "respawn" to a part of your game to test.
