I’m reading The Magic of Thinking Big right now. It’s my current ‘Sit up straight’ book. I’m also reading a few others concurrently, more abstract stuff like Notes on the Synthesis of Form, and about to start a Bill Bryson book called At Home.
This is my typical pattern, to read a handful of books at once, and I’ve found it always helps if one of those is a ‘Sit up straight’ book. SUS books are those packed with practical wisdom and inspiration. The kind that you can’t read while slouching or you’ll be in contrast to the ideas in the book. I can’t read a lot of these books, and I don’t read more than a few pages at a time, but interspersing other readings with some SUS is a great way to keep me from getting pulled too deep down the thought hole.
