This is a great book that reinforces ways we can increase use of our brain power to learn rather than the small percentage we actually tend to use. My only drawback is that the example given is to learn a foreign language, which is mostly memorization. I read this book hoping to help me learn calculus and statistics. I'm sure the information I learned here will help me memorize formulas and so forth, but the actual application of the knowledge will still be a struggle for me. Maybe I'll be pleasantly surprised though.
