I found Peale's "The Power of Positive Thinking" to be quite inspirational. The book focuses on simple ways that you can change your thinking to be more positive and the ways that it can affect your life. I read this book a little over a month ago, and it has honestly changed my life. I find that my relationships with friends and family are stronger, less arguments. I am more satisfied with my life. I found the tone of the book to be comforting, he tells the story the same a way that a father would give advice to his son, using real examples from his won life and passing down his wisdom. There is a lot of biblical references in here was well, so people with more religious tastes will surely enjoy it. If you have any spare time at all, even just a few moments a day, I would highly recommend this book. It will change your view on everything.
