This book has covered lots of different topics. I believe that, right now, it has all become a big mess from which you can only remember bits and pieces. I know I can't handle it all in my head at this moment. There's just too much information packed inside.
To help you remember as much as possible, this last chapter will revisit all the topics of the book, chapter by chapter. I'll repeat the most important ideas from each chapter, while you can just relax and remember all the details. For good measure, I'll throw in some additional tips, tricks, and techniques that didn't find a place in the "regular" chapters.
