If you know the answer then you don't have to read on.
Yes, of course the answer is quite obvious. But something always happens when I read. It just wasn't until reading along in this book that I actually noticed what was going on. Before it was just automatic and I never paid any attention to it. I'm sure you've noticed that when you're reading you often get sidetracked and you start thinking about something else (sometimes related or unrelated). Isn't it interesting how you can keep reading on and on while at the same time drifting off into that thought that just popped into your mind. It isn't until you stop yourself and say.. "Wait a minute.. what am I reading..?" then you have to backtrack to understand what you had read. While doing just that I paused and realized what was happening. My first thought was "come on now, pay attention.. this is important stuff I have to read.." Then I thought about how that stuff that I randomly started thinking about.. those thoughts would not have been triggered unless I had read what I was reading before my thoughts began drifting. The other thing I noticed was..
You know how at times you just think to yourself. That internal dialogue about different thoughts and ideas. Well, when you do this - on your own - you can only have that internal thought process about the things that "you already know." When you're reading a book (such as a non-fiction self-help type book), that same internal dialogue is taking place while reading; however, you're not pulling knowledge from "what you already know," instead you're pulling the knowledge "from the author of the book." Granted this has always been this way, it's interesting to me when you actually realize what's taking place. So, you don't have to feel guilty when you get sidetracked (usually) because those thoughts are spawning from "the authors knowledge - as you read."
