Even when you know things, sometimes a gentle reminder is needed. Just like we often aerate the soil for plants to grow well. Our thoughts and knowledge too needs tilling from time to time. This is one such book, which fills us with that freshness. A gentle nudge to focus on things which are easily overlooked, in the name of busy life. Author does not dictate to follow any sequence to read the book but leaves us with a suggestion at the end of each chapter. A simple, thought provoking, and easily executed book. Do read.
