But all the artists that never completed a work because they always thought "it's not perfect yet" are forgotten, by everyone.
Measuring the "influence" of an artist my "number of artworks created and sold" is a bit like measuring academics by "number of papers published". It's at best a very coarse approximation of "the real thing". At worst, total bull.
Tolkien being an example.
That anything came down from him was the executors of his will ignoring his stated intent.
And yet he's considered a literary Great of the 20st century.
Sometimes, legacy is that what others did.
