"Subtriangular" is a word in ENGLISH

I simply vowed to the universe that I would write forever, regardless of the result. I promised that I would try to be brave about it, and grateful, and as uncomplaining as I could possibly be. I also promised that I would never ask writing to take care of me financially, but that I would always take care of it - meaning that I would always support us both, by any means necessary. I did not ask for any external rewards for my devotion; I just wanted to spend the rest of my life as near to writing as possible - forever close to that source of all my curiosity and contentment.
