I agree with this. No matter how much I love the company, their mission, or people I work with, it’s not healthy to work 7 days a week and 10h a day for the company that you are not an owner of. Boundaries between job and life are flexible, but not as much.

I’d rather spend 10h a day 7 days a week pouring efforts into my own assets, or towards my vision, and not for someone else’s assets or vision, especially if I have no say and stake in the high level decisions (like sale of the company).
