- Perspective - You're never as cool as you think you are, since you never have access to enough objective data to make an accurate judgment.
- Purpose - If you ever think you're cool, the only thing you've done is wasted time in actually becoming cool and increased the probability that you are actually uncool.
- Propagation - If other people think you're cool, not only do they suffer from the same perspective problem, but they also could be lying. Believing them not only wastes more time in communication, but is less likely to be true.
Obviously, the point is to never think that you're cool. Ironically, the coolest people in the world usually don't enjoy their coolness.
