I think those people also are more likely to have the work life balance to pursue hobbies where most people doing fast growing/early stage startups are off balance. I personally don’t care what I spend my time on at work, I’ve found even when I enjoy the work, it doesn’t increase my fulfillment in life over the long term. So I try to optimize the life part of the ratio as much as I can, at times at expense of the work side of the ratio.
