When you try to apply guidances and frameworks from books and struggle to make them work in the real world, consider this perspective: the guidance you find in books are merely guides to touch up and polish what you need to do. They cannot contain everything you need to do. But they do provide advise that helps you polish what you need to do. Whoever wrote the book you are reading doesn't know your particular circumstance, so they absolutely cannot provide specific advice. But they can provide general advice. The value of knowledge contained in books is they expose you to ideas and experience that others have encountered and learned. It is still up to you to apply them appropriately to your situation.
