Multi tasking is not actual multi tasking. It is switching attention from one task to another very quickly. Our brains are bad at doing this, and the more we do it the less well we perform. It is better to concentrate on one thing at a time. This book explains why, and gives practical strategies based on sound scientific psychology that will help you to concentrate better and to remember more.
It explains why we find decisions harder if there are too many choices, and how to tackle that problem. It gives practical advice on how not to forget things, how not to run out of time, and how to use logic to make tough decisions, and not to be swayed by irrational emotions.
It also puts forward some ideas for education. What is the point of learning stuff when we can just google everything? The book explores what we should be learning, when everything is just a click away.
Really readable and packed with excellent (and commendably scientific) background psychology.
