Not to disagree on the topic but “if you can’t finnish it, don’t start it” is absolutely horrible advice when its about a creative art like writing.
If i am not wrong there is a whole writing style about just starting without knowing yourself where its going to end.
I highly dislike capitalism but i can see that once you have enough material to sell some of it, even if incomplete as a series. Many people would take the opportunity. I don’t know the authors economic background but for a starving artist with high potential that first book sales could be the push required to finish a series.
I blame capitalism, both for putting artists in this position and for the disrespect of big media towards their own content quality. Its always the money must flow, at every cost!
Multi-lingual inner monologue is awesome though.
So much of how we think is dictated by the language we speak. Many things can only be said in some but not other languages.
