Well, it's not quite what I was looking for, but I think it might help.
Quotidian Grace and I have been struggling with the time-management-to-prevent-burnout thing. There are some suggestions in this article from the Washington Post (and I do hope the link works, I don't use links often, so I am no expert at it). Some of it seems pretty obvious once it's mentioned (like much advice...)--say no, block off time to do certain tasks. The email one may really help--I tend to read emails immediately as they pop up. This can really contributes to my procrastination!
Procrastination and too much to do. I'm beginning to see a relationship here. I think one thing I do is delay doing the difficult tasks (or the ones I feel less comfortable with) by doing the other ones, which may or may not need to be done just then. So I end up with things done, but not the tasks that really needed to get done--they are still waiting. SO I feel like I'm working hard, but I'm really spinning my wheels.
Hmmm. I think I've hit on something.
