The word "work" is not specific enough in this context, and this whole discussion lacks nuance. When we talk about "work" are we talking about renting your own time, or building something you have a stake in? Does a side project that may give you insight into your main focus apply as work? Does reading and curiosity count as work? I spend nearly every waking hour trying to be successful... is that work? I'd like to introduce the word "toil" into the discussion. Elon Musk may "work" 100 hours a week, but there's no chance he's "toiling" 100 hours a week.
