Hi Andrew,
I know this is an older thread but I'm new here and I saw your question about Self Analysis, which is one of my favorite books, so I could not hold back from answering your question. I figure it will answer the question for anyone else who wants to know too.
The best way to get the most out of this book (Self Analysis) is to read the book making sure you don't go over anything you don't understand or any words you don't understand (see the note on that in the beginning of the book). I've found that you'll totally grasp the book this way.
Also after you've read the book through up to the processing section of the book, I've always found it best to set aside some time during the day preferably not too late at night (such as before 9pm) and to make sure you've got enough rest and are well feed before starting on a processing section each day.
I've done this for over a month (doing some of the processing each day) and got some really awesome wins! My memory improved so much it's amazing!
