Style becomes recognizable through repeated preferences too subtle to list.

Nobody writes down their style. It emerges from a thousand small choices repeated: the same interval, the same kind of light, the same rhythm of sentence, a colour that keeps appearing. Others can recognize it instantly and neither they nor you could produce the list of what it consists of.

This is a reason to make a lot rather than agonize over a single thing. Style is what remains constant across volume. You cannot design it in advance; you can only produce enough work for it to become visible.
