i often feel that myself often spend much time for the useless things.
why?
i often think about anything that in fact it's not important to think.
the result is :
my scores in class is falling down tragically..
huhuhu...
sometimes, there is a motivation in my mind to repair my way for learn or study,
but the motivation is just stay for a while.
when i want to do it, it's losing immediately..
it's so confusing me..
i want to cry as loud as i can..
i want to shout for everyone who is bothering me,
but i can't..
i'm to weak for that, i'm not strong enough to shout for anyone..
what should i do now?
