Sometimes you can try a hybrid, mixed version of the suggested photoreading technique and the direct learning method.
For instance, in this case you want to make adjustments to your self-esteem. I might try finding all of the best books out there - for instance, all of Anthony Robbins books, books like the Sedona Method, everything that you can find that might be of help on this subject. You might want to preview and weed out some of these that you feel aren't for you. This would leave me with a stack of probably 10 to 20 books, which I would have found at the library or while browsing at the local B&N.
I would photoread as many as I could, taking breaks for a drink of water between books, taking a day or three if needed. Then I would let it all simmer for another day or two - the main thing during this early process is your clear intention and purpose in photoreading the books - to change the behavior for the better. Also, doing the affirmation at the end of each book - "I release the information that I have photoread from my inner mind to my body and conscious mind to process. I am very curious as to how many ways my body and mind can show this information to be available to me."
Then, after a few days, go back and possibly activate in the suggested superreading and dipping methods a book or two. Just relax and know that there is nothing that will stop your modification of this behavior. It is inevitable. Your work with these books is like a river of knowledge that is carving a beautiful new landscape into your personality. Keep with it and maybe even photoread the stack of books every now and then just letting that information continue to simmer and knowing that it will activate through direct learning and maybe consciously activating another book or two every now and then.
Just keep at it and know that nothing can stop this process of growth and change. It is like the shoot slowly but surely growing from the seed, which can and will break through rocks, cement, etc., as it grows into a magnificent tree.
