My opinion, confident as it may seem to some, is based on years of experience and personal success. As a writer, I opine on what has worked best for me and my circle of colleagues. And most publishers prefer that writers working with them are organised enough to produce work that is profitable.
Yes, not every single writer uses the ‘Have a plan before executing’ approach, but a good majority do – as it is quite evident in the Poll result so far.
And again, at no point have I stated that such is always the case, so for you to come back and say that ‘it’s not always’ the case makes no sense. You just assumed it, as much as the other person you quoted has.
All of this is just going round and round in a meaningless ellipse, so let’s agree to disagree and get back to writing stories.
Cheers!
