I can never believe how much I am sometimes capable of accomplishing in a day. And some days I cannot believe how very little I manage to get done. For me there is ALWAYS one thing that makes the primary difference between a productive day and a non productive one -- a list.
If I put 10 or 15 minutes worth of thought into planning out my day and listing all the things I will do and when I will do them then it nearly always gets done or at least very close to done.
I haven't marked off the laundry yet, but I have gotten it all done and all that is left is the blog -- and I'm almost caught up!
