NOT doing what I planned

Even when I find free time to do whatever I wish to do, I find myself NOT doing what I had thought that I wanted to do. I've been wanting to answer the letter received in the mail this past week; I've already thought of complete sentences to write, in my head. Just haven't actually written them down.

I also have stacks of books and old art magazines that I've been reading through, a bit at a time. But instead of any of those things, I found myself drawing what was piled on the footstool in front of me.
