The best thing for being a writer is having a hopefully positive influence on readers. To inspire, educate, and in my case empower them to expand their horizons. Even if it means they disagree with me or my premise. It still means exposure to a notion they would otherwise not of conceived of on the basis of my writings.
The other blessed aspect is to have a devoted loyal following of an audience that appreciates one's work. Otherwise this calling would be completely self-serving as a therapeutic benefit without sharing it with the public at large.
