It was really more of a book about the need for thinking than a how-to manual, but the checklist in the back was a good one and the examples in the book did highlight those principles without really drawing out particular applications. Jacobs is an excellent practitioner of writing as a craft; his words and examples were all carefully chosen to achieve his effect and reach his audience.
Even if I would have preferred he came out more boldly throughout, still it was evident that he was masterfully choosing his words. Noticing and thinking about how and why he expressed himself throughout was of more benefit to me as a writer than his actual words.
From the Amazon description: “How to Think is a contrarian treatise on why we’re not as good at thinking as we assume—but how recovering this lost art can rescue our inner lives from the chaos of modern life.”
