Firstly I suggest you start by accepting that you are probably doing it right.
From your post you have negated your efforts every step of the way.
Relaxed enough. If you take a deep breath and exhale you are more relaxed than you were a momment before. Simply start by doing the relaxation exercises as given and take it for granted that you are relaxed enough. Saying the chant will keep you there.
If the blip page gives you trouble use the X-technique explained on page 48 of the book. All it takes to be in photofocus is a soft gaze that sees both pages of the book.
Set time limits for activation and stick with it. You'll need to motivate yourself to stick to activation rather than regular reading when you. Remember it will take more than one activation pass to get what you want out of a textbook.
If you have the course you have the memory supercharger tape. Use that often. Use it to remember how it feels when you are relaxed. Use it to remember how it feels when you successfully activate. Use it to remember your homework and study material.
If you haven't got the course you might want to obtain both the Memory Supercharger and the Personal Genius tape. As an owner of a Light and Sound devise I can assure you, you will gain much more from those 2 tapes and it will cost you less.
