So I tried an all-administration day like I discussed in a previous post. In short, it didn't work. I'm not a professor so I don't have enough administration to fill up a day. I ended up doing some stuff for half the day and then sitting around my room goofing off the rest of the day.
The problem is that I chose Thursday which is my least busy weekday. What I should have done is piled all the administration on Wednesday when I have two classes and am pretty tired by the end of the day. But Wednesday is not so busy that I don't have time to do administration at all. So I think the key is to pick a day that is busy but not too packed.
