Price: $13 on Amazon What I love about it: You can flip to any section and find some “new way of looking at a problem” in this book. It gets you to take existing problems you have, and flip them around in ways you never thought of before. Apply the lessons to your copy to find new “angles.” What skills you’ll learn: Problem solving. Looking at a problem from different angles. Tone of voice: Informative and fun. Reading Level: Beginner.
