I try to work as much as possible - to the edge of sanity. Every good hour or even minute of thinking about Tesla or SpaceX has such a big effort on the company. It makes sleeping difficult.

Insight: There's something almost reckless about this admission—the idea that the most important work demands you sacrifice the very thing that makes you functional. Most of us experience this tension at smaller scales: the project that keeps us awake at night, the problem we can't stop turning over in our minds even when we're exhausted. Musk is simply naming what many high-performers quietly know: intense focus on something that matters genuinely does make rest harder. But here's what's worth noticing: he frames this as a feature, not a bug. He's not saying the sleeplessness is a problem to solve—he's saying it's evidence that the work is important enough. This reveals something about how driven people think differently. They've made a trade, often unconsciously, where the inability to switch off becomes proof of meaning. The question is whether that trade actually pays dividends or whether it's just a story we tell ourselves to justify burnout. The real tension hiding here is that sleep deprivation actually degrades thinking. Your best ideas don't come at 3am when you're wired; they come when you're rested. So the paradox is this: work hard enough to lose sleep, but lose sleep and you'll work worse. Maybe the actual edge of sanity isn't staying awake as long as possible—it's knowing when to step back so you can actually think clearly.
