For everything that we succeed or don't succeed to accomplish in life, we use a certain strategy. We use the wrong strategy if we don't like the results we get.
You need to become aware of how you are doing this mind wondering. This doesn't just happen outside of you. You are creating it, albeit unconsciously, that's why it feels like it's happening to you.
Watch yourself what do you do when you start reading. Do you loose motivation? Do you think about things that seem more important? And whatever the method is, change it. If you start thinking in your mind, change the voice. If you are getting visualizations of some place change that. Basically you need to break the pattern you are using to help yourself wonder.
