Shortage of enthusiasm

Mentality empty at times. Somehow or rather feeling very out of sort these few days. Brain not willing to work every times I try to make it work. No, I don't think it is a loss of interest. The interest is still there but somehow I couldn't pick up the enthusiasm or mental strength. Don't know why. Sigh...

Anyway I have passed the oral exam, so now the only thing left is the final thesis defense which will be (hopefully) done in 2010. Seems like such a long way to go and yet sometimes I can't help feeling time is short, afterall haven't really make any big progress in my work. Well guess they always say "take one step at a time". Just hve to do that.
