Good For Nothing

Lulzy Existence.

If someone is Good For Nothing, they can't do anything right, important, interesting, or meaningful. Somebody who's Good For Nothing might not be aware of being so, but if they are, they'll lose their sense of self-worth. The task of telling someone they aren't Good For Nothing may prove difficult as they're right most of the time. But when they're needed to pull of some incredible stunt like save the life of their friend from some time-sensitive danger, they receive God-Send Skills to succeed and show that they aren't so worthless after all. Somebody believing that they're Good For Nothing can be used as bait for a "you're just fine the way you are" moral at the end of the plot.
