What does your current way of thinking get you? Do you have tangible evidence for that? Not just "it's my way of thinking, and I create output, therefore", but the causal relationship you demand from this book?

"How to think" is always subjective, and additional ways to think get us additional tools in our toolbox. I'd strongly recommend you at least skim the book, and see if it's applicable to your world of problems. (It's 166 pages and "mostly pictures", so it should be a quick read - and it only needs to make minimal impact to repay the time you spent)
