When I read books and newspapers. I've noticed if the book is too close, the words gets blurred. I have to remember to move the book or newspaper further away, to as far as my knee, when I can see the words clearly.
It's good to have distance between me and the words, between me and the world. Only when there is distance can I see things clearly.
