I have problem with concentration (or being focus) at something. For example, if I do play a certain online game. Later a minute or several minutes, I would quit even though I am with other players partying (by party I mean together killing, yes killing online games mobS)

mobs there or so, chatting, or so). So I become a very very bad teammate.
But what upset me now is I can't focus reading. I am a bit perfectionist though so I think that contributes somehow. I want to flip pages smoothly and I do not want any page to have scratch or else I get very upset.!

Especially when the book is new.
SO earlier, I tried to read a certain book. I really can't follow some texts there, (I mean I can't comprehend what it talking about) so I just try to focus reading the next line. But I really can't move on. I think my mind says that I have to understand it first before taking to the next level.
If I can't understand something and continue reading, my mind is like going to bomb and I want to throw tantrums.. I get very upset.
I also get very very very dismayed when my goals not reached and therefore I can't concentrate anymore...
SO what do you think my problem maybe?
