Query: Gave me a new perspective on things

This book is pretty short and you can probably read it in one long sitting if you wanted to. However, some of the ideas you really need to let sink in so I wouldn't recommend reading it in one day.The whole book can be broken down into one idea. This idea is that everything that happens to you is for your benefit. The things that seemingly would be negative are only negative because we react negatively to them. If you lose a job, you think it's terrible and it causes stress and anxiety. But what if after you lose your job, in a month you find a better job that pays more? Then you shouldn't have worried at all in the first place.This book might not change your life, but it will help you to think more positively. It's a very good, easy read.
