I have learned to use the word ‘impossible’ with the greatest caution.

Author: Wernher von Braun

Insight: We throw the word "impossible" around like it costs nothing. Something's too hard, too expensive, too risky—suddenly it becomes impossible in our minds. But what von Braun understood through actually building rockets was that impossible is often just another word for "I haven't figured it out yet" or "nobody I know has done it." The tricky part is that sometimes things genuinely are impossible. You can't break the laws of physics. But most of what we call impossible in daily life isn't physics—it's just the gap between where we are and where we'd need to be. That job seems impossible to land until you talk to someone who landed it. Learning an instrument feels impossible until you find the right teacher. Changing a relationship pattern feels impossible until you try something different even once. The real caution von Braun is suggesting is this: when you catch yourself saying something's impossible, pause and ask what you actually mean. Are you saying it's hard? Too uncertain? Nobody's done it around you? Because those are all different problems with different solutions. Impossible deserves to stay rare and special, reserved for actual laws of nature. Everything else might just be waiting for someone stubborn enough to be cautious with their language.
