Byrd’s Law #93: The worst sin in marketing is to be boring.

The only thing I have to add is: Boring to the people you are trying to reach! If you are selling fast cars, it is perfectly okay to be boring to little old ladies.

And the only thing I have to add to that is: The only way to know if what you are thinking is going to be boring, is to put yourself in the shoes of the person you are trying to influence.
