Procrastination and perfectionism often go hand in hand. Perfectionists tend to procrastinate because they expect so much of themselves, and they are scared about whether or not they can meet those high standards.
I know that I have procrastinated getting my daily picture done. The first day I missed I thought to myself, "I will do 2 tomorrow". Know I am a week behind. This is harder then I thought it would be. I have a few things I will be doing this weekend. I should be able to take some good pictures.
