People say to me - This couldn't have taken very long to write.
It only took me a half hour to write this 200 word picture book.
But it took 3-5 years to revise/ submit/ revise/ submit/ revise/ etc. etc. etc. (and some picture books take even longer to "write.")
And then there's the 5-year wait for the illustrator and art director to polish up the book.Plus revisions to support the art.
And now books are being delayed because most picture books are printed in China and there's an epidemic over there.
Eventually, after the Advance has been paid off, the writer begins to get royalties from each book sold. (I get 2% for two of my books because I share the royalties with a co-writer, 4% on all of the others. Famous writers get 5% to 10%.)
(don't get me started about requests for free school visits or lecture for adults with no compensation except sometimes they buy ONE of my books for their library, which means eventually I'll get about $0.87 [cents] six months later when my royalties arrive. For that all day/ 4 or more group sessions, plus that 40 miles away drive to get there - and to get back, exhausted.
