Success Quote by Guy Kawasaki

"A good idea is about ten percent and implementation and hard work, and luck is 90 percent"

About this Quote

Guy Kawasaki’s provocation lands like a cold shower on startup mythology: the fetish for the “killer idea” is mostly a comforting story founders tell themselves when the future is still malleable. By allocating a measly ten percent to the idea, he’s not denying creativity; he’s demoting it from sacred object to entry ticket. The real flex is in the lopsided math that follows: implementation, hard work, and luck aren’t separate lanes so much as a chain reaction. Execution increases your surface area for luck, and relentless iteration turns random breaks into repeatable outcomes.

The subtext is both humbling and strategic. Humbling, because it punctures the ego-driven belief that brilliance deserves a market. Strategic, because it reframes what founders should actually optimize: shipping, distribution, timing, hiring, and endurance. Kawasaki came up through the Silicon Valley era when products lived or died not on novelty alone but on ecosystems (platforms, channels, partnerships) and the ability to ride a wave you didn’t create. His “90 percent luck” isn’t a surrender; it’s a warning against confusing narrative coherence with causality.

There’s also a quiet ethics to it. If luck dominates, then success is less proof of personal superiority than evidence of alignment with circumstances: the right customers, the right moment, the right constraints. That perspective doesn’t kill ambition; it makes it sturdier, because it teaches you to build like you might not get lucky, and to stay ready when you do.
