This is one of the best books I have ever read to be sure. I am a writer-hence a highlighting and marker up of books and this one I couldn't stop starring paragraphs and excerpts and folding over pages for important points. This book is for teens but I highly recommend it for adults as well. I read this book from start to finish and got the best advice ever! It definitely helped me to increase my ability to think positively as well. I can also pass this book on to my daughters when I am done with it and they will get the same great tips and advice and hopefully use it to the best of their ability as I am doing! I highly recommend this book to teens and adults, young and old, we all will benefit. I am definitely going to read this book again! ( )
