There are two key pages on this site. Each takes less than 20 seconds a week to read. With either of these, you will need nothing else. They are clear, short, complete, simple, action specific. See to believe. Past samples: one, two.   free trial

    The rest of the site is full explanation, abundant details, and extensive documentation with ample comparisons and illustrations--all optional, at your convenience. The letters alone provide you with total, brief instructions for weekly action. Use either or both.
