mein aisa kyun hun?

It is so hard to keep the motivation going. Now that most of work is done although some experiments still need to be finished, it is hard to keep the motivation to write it up...I am trying to find any excuse not to work on my thesis...chatting with friends, browsing net, music, TV, football, writing this blog, reading other blogs....anything works...I need a vacation...someone tells me from within...what to do...
