If you need to learn how to argue intelligently, you don’t have a real argument;
if you need to promote, you don’t have anything to sell;
if you need to network, you don’t have anything to offer;
if you need to prepare for a lecture, you don’t have anything to lecture about;
and if you need to learn how to improve your style, you don’t have anything to write about.

Truth is direct; it screams and doesn’t meander.
