Being one of the chaps who has built to do list apps in the past I think what you're trying to say is that everyone is different! Some people need lists to keep track of their lives, others prefer to live life without them. And you're the later. At least in this digital age we have choice and competition. From a developers POV building a todo list application has helped me learn new skills, techniques and programming languages. http://todomvc.com is wicked for that sort of thing.
