Yes, but there's an inherent, almost clear expectation in this treatise that you do in fact, 'eat it' or at least stay those hours.

If you're staying >10 hours at the office the least they can do is get you dinner, but when it starts to be a cultural expectation it's going to be a long term problem.

The way most equity is shared - if you are working 10-12 hours a day and the company is not growing wildly, i.e. looking like a Unicorn - it's probably not worth it, and you've drunk too much koolaid.

Koolaid and hard work are good, but I think the goal is kind of 'self aware Koolaid' ...
