I disagree but I think my interpretation of hustle may be different than yours.

Buffett for sure hustled. In his early years the dude was doing newspaper routes and running small businesses.

He spent endless hours, neglecting his family, to devour the moody’s manuals and find bargain investments. Some of these he had to work hard to overthrow the management, including Berkshire Hathaway.

Buffett is constantly working, more than a traditional blue collar worker.

Yes, a good chunk of that is behind a desk but to me that’s hustling.
