Ask HN: Why do I hate software planning tools?

Can someone help me understand why I've never been able to use software planning tools? One contract job I have wants me to plan the tiniest details of what I'll be doing and how I'll be doing it a month ahead of time (using _Rally_, if that helps).

Most of my work is creative programming and problem solving. I'm constantly solving problems that I've never done before and due to the nature of the environment, probably few other people have done before either. How do you schedule innovation?

Am I just a sucky planner? Is there anyone else out there who can come up with a better answer than "I'm figuring that out" or "I'm working on it" when asked what's coming up next? I'm not even sure if this is the right question.
