I found his thoughts on stamina and research particularly interesting.
Here’s an excerpt:
When I read a book, I am looking for the essential elements in the work that can be used to create the strategies and stories that appear in my books. As I am reading a book I underline important passages and sections and put notes (called marginalia) on the side.
After I’m done reading I’ll often put it aside for up to a week and think deeply about the lessons and key stories that could be used for my book project. I then go back and put these important sections on notecards. A good book will generate 20 to 30 notecards, while a bad book will generate two or three notecards.
