If you look at space companies, they've failed either because they've had a technical solution where success was not a possible outcome, they were unable to attract a critical mass of talent, or they just ran out of money. The finish line is usually a lot further away than you think.

Insight: Most ambitious projects don't fail because they're too hard—they fail because people miscalculate the distance. You see this everywhere: the startup founder who expected product-market fit in six months but needed two years, the person trying to build a side business while working full-time who dramatically underestimated the stamina required, the team that solved the technical problem brilliantly but couldn't keep the lights on long enough to reach customers. The finish line shifts the moment you stop looking at it as a fixed point and start seeing it as something that requires constant recalibration. What's interesting is how this plays out psychologically. We're wired to be optimistic about our timelines—it feels motivating in the moment—but that same optimism becomes dangerous when it leads to running out of resources before the actual finish. The real skill isn't having a vision; it's being brutally honest about the three things Musk names: Do you have a path that actually works? Can you build a team that won't burn out or leave halfway through? Do you have enough fuel in the tank? The implication is almost unsettling: success isn't about being smart enough or working hard enough. It's about realistic resource planning, keeping talented people engaged over years rather than months, and stubborn honesty about what "done" actually looks like.
