Problem Solving 101 was originally written for Japanese school children by Ken Watanabe who wanted to shift the focus from memorization to critical thinking but has become a popular guide on how to achieve your goals. It's a quick read, but one that will make you think differently about solving problems. The book comes up with a 4 step process that can be applied to any problems or goals you would like to achieve. And the drawings and diagrams make this very easy to understand.
