time waster

I am such a time-waster.
I spent 1 more hour everyday hanging around websites with various meaningless posts and news. when back to myself, face to my laptop, open my papers and books, i realize how many things left to me. how could i make all those done in time! then maybe for 1 hour or 2, i will be engaged in my works and i would find hundreds of reasons to get myself relax after that and wander on internet. how am i supposed to do to get my self screwed up?
