The 5 Elements of Effective Thinking
by Edward B. Burger · read October 10, 2017
One of those books that you should have a copy of just to thumb through over and over again. It's not revolutionary, but it's a great collection of techniques and strategies for thinking that I think anyone would enjoy. The book is compact, well organized (I love the 'elements' mnemonic), and very practical - plus, it has its own outline at the back, which I think is absolutely fantastic.
