The key for me is to trust the process. The best way I have found to establish that trust is to do the course exercises. Set up a purpose and then try doing some dipping.
When I first did this I only ended up reading a few sentences and I started thinking that it wasn't working. To my surprise it was working. When I read over the whole article I discovered that the sentences that I had dipped were relevant to my purpose and the rest was filler (so it worked).
Practice and testing out different things is the key to catering the course to your individual needs.
