On top of that, most of the most successful people on the planet write little or nothing. They are too busy doing.
You state this as fact without providing a dataset to back it. I think this is not true at all.

It depends on how you define "success".
I would consider people like Linus and Dwayne Richard Hipp and TBL to be among the most successful people on the planet, and they write quite a lot.
Do you call people who capture then give away a billion dollars the most successful? I don't. To me the most successful are the ones who create billions in wealth and capture just a tiny fraction--enough to support their family and friends and live a good life.
Look at your own comments. My comment is effectively "people whose day job is to write, write the most". It's borderline self evident.
Your argument has devolved into: "people who write a lot are by definition successful. I wonder if there is a correlation between writing a lot and success."
