"I wish I could write a beautiful book to break those hearts that are soon to cease to exist: a book of faith and small neat worlds and of people who live by the philosophies of popular songs."--Zelda Fitzgerald

Whatever you have done, whatever your book, make it one that you have wished to write.  No matter what, then, you will have done something.  That it is or is not published does not belong in the same day's discussion.
"The new always happens against the overwhelming odds of statistical laws and their probability, which for all practical, everyday purposes amounts to certainty; the new therefore always appears in the guise of a miracle."
--Hannah Arendt

That said, good luck, and many miracles.   ###
