If you want to make an actual living, then write 15-20 midlist books (or 5 bestsellers) and revise them regularly (the real money is in the revisions, not the first editions). You can drop a note to an acquisitions editor to see if any authors have refused their right to revise.
Even if you lose money writing a book (you probably will--that's why editors rarely quit to become authors), you can still impress at contractor interviews by showing up with your published book. Or use the book to raise your speaking fees, etc.
