Hello. I wrote a drama piece months ago and it's already on the way to publishing. It's being edited.

I've been having this feeling of maybe the book won't be 'successful' as I imagined and even got discouraged to a point of almost halting the publishing process.

My questions go thus: what makes a book successful? Is it all about good writing, editing and cover design coupled with efficient distribution? Because I feel there would be many good books that would have been published but never got their due recognition.

Or am I just been weird?

HELLO.
HOPE BY NOW YOU HAVE GOT YOUR WORK PUBLISHED
