I was really shocked how this one simple things called self discipline is important in life. This is what really differentiates successful from unsuccessful people. A must book and very simple to read.
Flow of book as well as interest level of reader may change from topic to topic since effectiveness of the chapter changes significantly. Some of the chapters appear to be quite common sense and therefore rhetoric. However, some chapters are great and make you think fundamentally about your approach towards achieving goals in your life. I liked reading this book.
