"The older a man gets, the father he had to walk to school as a child." (Henry Brightman)
For writers that could be paraphrased as, "The older a writer gets, the longer it took him to get his work published."
The longer in the tooth a writer is, the more they forget the short stories and the book reviews they wrote etc. They also forget the writing they weren't paid for that got their name out there.
We're already published writers, we just haven't been paid or recognised yet.
