Hello, I'm now having another problem.... For example, if I listened to song before pr, then during pr'ing, the song always stay in my mind, and distracts my concentration, this is like I 'hear' the song in 'my mind'. Does anyone face the same problem before ? Please give me some solution to solve this problem.
And, I think I achieved some result in pr'ing, that is I pr the NeuroAnatomy text book for 7 times contineuly, I only stop for few second in the interval to refresh my mind. Then I try activate it on next day... somethings funny was happened, I feel than I know many things from the book, but if I ask my mind what is it actually, the feeling gone. I experienced this kind of feeling through out the day. And I uesed to read it regulary, I found that I'm much more easy to memorized the facts... but, seems its not like 'long term' memory yet, I still forget most of it few hours later. For addition, I only have the feeling of knowing somethings when I pr the same book for many times.
Then the photo focus step... I can see the blur blidpages, but the double line always disappeared when I turn the page, but I can immediatly see the double line again after turning the page, is that ok ?
Realy thank for reading it, wish all of you good luck and all the best. Takecare.
