What is the self-sabotage?

We go through the motions of trying, but incompetently, so that in the end we fail. We wait to speak until there's not enough time to deal with our concerns. We conveniently forget our materials. All our points suddenly disappear from our head. And voilà! All of our interests are satisfied: we can feel good about trying, and secretly satisfied that we didn't succeed. This is the art of self-sabotage.
