To do list

Why is it that I have all this energy while I'm sitting here at work, listing all the things in my head that I want to do when I get home then when I get home I don't do any of them??

I need to do my taxes which terrifies me.
I still have some files to organize.
I need to finish my quilt.
I need to do some homework.
I need to organize my work clothes.
I need to create new playlists in Itunes.

These are not difficult tasks but I just fade away when I leave here.
