You could apply the same logic to almost any passion that a person can have. Tennis, racing, singing, pick your choice. I was up till 1am last weekend playing tennis under lights. Overdo anything, and you're likely to get messed up.

I think you're reading too much into it. It's just a pitch, effective or not and I think it relates more to deciding to go for the idea and the "Eureka!" moment rather than the weeks and months working on it after doing so.

I agree -- work isn't the only thing you can burn out on.

But I do think it totally relates to the weeks and months working on the start-up after the "Eureka!" moment. I'd say "having the idea" is the "Eureka!" moment in their slogan, and they're referring to eschewing eat and sleep in order to make that idea a real thing. Which takes weeks and months. Which sounds like a recipe for burn-out.

And, honestly, I think entrepreneurship should be approached soberly rather than like some extreme sport or gameshow. Because start-ups can lose you hundreds of thousands of dollars in opportunity costs, potentially, and interrupt other parts of life. Not that they aren't potentially rewarding as well, but the stakes are high and should be treated as such.
