Thank you for your advice

But I am still pondering about the last question you asked "Do you start to daydream?" Does it means that my mind wanders off? Yes, I do ocasionally think about this and that but still able to remain in soft focus. As for my photo focus, I still have doubt whether I am doing it right or wrong. You see, I don't look straight through the book to get the blip page. What I do is turn everything into a "blip" where (I think) everything is blurry and overlaps with each other, then I centered the book infront of my eyes to get the blip (which is about one to two inches wide btw)
