I don't have that book on hand
A dream I had just the other day, may have tried to tell me the same thing that you said. After breaking it down, I came to the understanding that I am gorging on information and not taking time to allow the subtleties of the small amount of information that I really need to study to sink in. It is like saying that I need to pay attention to the little things, the subtle things.
All through my youth I had to hid things from my parents so I studied when I could and tried to get as much information as I could… Now I do not have to pack all this extra information in. It is like I keep forgetting it, or maybe I may still be fearful that I will not get a chance to learn the information later on...
All I know is that I need to remind myself to study just what I need to study... Very often... And I am often distracted by other things that I feel are more important as if they cannot wait till tomorrow.
