Sometimes I just have too much on my plate, and it has the effect of making me completely unproductive.  Not unproductive like "I wish I could get more than 3 things done today", but more like "I wish I could get a single thing done today".  And it's not like I have any lofty goals or anything like that.  I just want to check out a few websites and do a few little meaningless things.  But because of the shear number and complication of those things, I end up doing nothing at all.  This is definitely a problem. 

Update (2007-01-23 3:08pm):  Maybe I am task-oriented.  All these things on my to-do list don't necessarily stress me out.  It's the fact that I'm not completing any of them.  It's not that I'm not trying.  I try something and get nowhere, so I move on to something else.  In the course of an entire day, I don't complete any single task; I merely chip away at a part of each one.  And it's sorta killing me.
