The best thing I can think of, that will help you the most, is to actually sit down and go through the chapters and the lessons.. At first it may seem like you'll be overwhelmed, but in less time than you think it will begin to sink in.. When it does you'll find you have the most useful tool you could imagine at your finger tips.. It is so much fun..
In order to make that process easier, get the book spiral bound so that it will lay flat.. doesn't cost much and makes it so much easier to use!
keep sticky notes and a pencil handy.. make notes to yourself.
