I do not recommend writing to any young person seeking a lucrative career. It is easier to make money off writers than to be a writer. This seems a bit screwy, since the author is the one doing all the difficult work.
I recently published a new novel as ebook. I make a bit of money and the publisher makes a bit of money. There is no paper involved, so no printer makes money. Sales are conducted over the internet, so retailers make no money (unless the title is sold on B&N, Apple, etc.) Still, the author earns more per sale than with print books.
Once the long struggle with writing is over, it is a pain to convert a book from ebook format to print format and vice versa. Once done, it can be uploaded to a number of print-on-demand publishers. I choose Amazon for my latest book, just for fun. To give you an idea of the economics (so you don't think that I am becoming rich), I earn $.62 per book, whereas Amazon collects $14.33 per sale. That's capitalism...
Prior to writing novels, the author enjoyed a multifaceted career: from decorated combat aviator to advertising professional to global communications director of a major consumer brand. He has traveled the world and met sports, film and television stars, political leaders, and royalty. He graduated from Middlebury College, is married, lives in Germany, and has two grown children.
