My college English-literature teacher taught us that there were only seven great themes in all literature, so every book, movie, or play embodies one of theose themes (or principles) in all of investing, but not many. Almost all of the best growth-stock investing revolves around certain themes of how a company makes its money, grows, and thereby provides great stock wealth to its shareholders.

When we can recognize things that have occurrred before, investing becomes much more simple. Each great company  has a business model that it should describe in very straightforward terms: how it will grow, be very profitable, and protect itself from competitors. Learning to recognize the things that really matter gives you that critical focus and helps you avoid drowing in the flood of informaiton available in this information age.
