Query: Obvious solutions with little insight

Overall, this is a nice book and a good topic. However, this book focuses on topics and ideas so obvious, I found myself muttering things like "No kidding" as I read it. Topics like 'Coin a memorable phrase' or 'Seize the day' or 'Develop your persuasion power' aren't new and don't uncover any new territory. If you can get this in used condition it might be worth the cost. Otherwise, I would look elsewhere.
