The distance between insanity and genius is measured only by success.

Insight: We live in a world that judges ideas almost entirely by their outcomes. The visionary who predicted a market shift looks like a genius at the finish line, but during the journey—when they were staking their reputation on something nobody else believed in—they looked like they'd lost their mind. Same person, same conviction, completely different reputation depending on whether things worked out. This matters because it reveals how arbitrary our categories really are. We're not actually equipped to spot genius while it's happening. We can only recognize it in hindsight, once the results prove the person wasn't crazy after all. The uncomfortable truth is that some truly visionary people will fail and be forgotten, while others will succeed through luck or timing and be remembered as geniuses. The gap between them often has nothing to do with how sound their thinking actually was. The real insight, though, is personal: it's permission to think differently without needing permission first. The people doing interesting work now—starting something unconventional, pursuing an odd passion, believing something unpopular—aren't necessarily crazy or brilliant. They're just committed to something that hasn't been validated yet. Whether they end up looking insane or inspired depends partly on skill and timing, yes, but also on simple stubbornness.
