It's not just about being a part of the problem, it's about being the problem.
A self-exception is when you're so caught up in your own head that you're creating your own problems, and then you're like "see, I told you this would happen."
Example: you spill coffee on your shirt and then you're like "well, I guess I'm just a coffee-spilling kind of person now."
