When you're getting into state and using the tangerine technique, don't doubt yourself. the reason you dont feel anything is because you are looking too hard. once you try to notice a difference, you'll find that there is no difference at all. the point is to be aware of the top back part of your head, and just read. if you find that you read faster, like the reading test in the learning course will demonstrate, then you know it works. you won't notice the change until you know exactly how it feels, but the point is to keep doing it, and then after you've had success with it, you'll know it worked.
