Ozy, which I try not to read, had a profile of James Park, who heads up FitBit. How does he stay ahead? The tagline from the article is:
In a behind-the-scenes interview from OZY Fest 2017, James Park shares his tips for success: sleeping five hours a night and always preparing for the worst.
When you delve into the article (and I don't necessarily recommend that), it's a bit more complex.
Park: I only get five hours of sleep a night. I know that’s bad and I need to work at it, but it’s gotten even harder as I’ve gotten older. I just find it difficult to settle my brain at night.
Damn straight its bad.
