Or because your topics are devoid of interest for any numerous body of persons.
Or because you persist in sending your articles to the wrong papers.
The first defect ought to be remedied speedily. The second is more difficult to deal with, and the third is most difficult. The eradication of these two will necessitate careful and continuous study of journalism in all its manifestations, and nothing but successive defeats will teach you how to be victorious. However, perseverance granted, the hour will come when an article of yours finds its way to the composing room. A day of ecstasy, upon which every disappointment is forgotten and the way forward seems straight and facile!
As soon as you can rely upon selling one article out of four, count it that you are progressing.

As to remuneration, a few papers send out cheques at regular intervals without putting their contributors to any trouble in the matter. Others, and among them some of the best, never pay till a demand is made. Some, including one or two organs of note, never pay till they are compelled to do so. If a remittance is not received during the month following publication, it is advisable to deliver an account, giving the date of appearance, exact title, and number of pages, columns, or inches.

This is because her eyes have not been opened to the limitless possibilities for the making of good "copy" which exist on every side. Most probably she has been looking in quite the wrong direction.
