Ben Horowitz: even Zuckerberg had the fear
a16z cofounder Ben Horowitz just dropped some real talk on betting on yourself, revealing that even Mark Zuckerberg, back when he was 22 and building Facebook, was riddled with doubt about whether the whole thing would actually work. Horowitz's point: doubt isn't optional for founders, it's universal, even for guys who end up running trillion dollar companies. The lesson landing hard with startup Twitter is simple: feelings are irrelevant, actions are everything, and if your guts aren't boiling you're probably not trying hard enough.
Nothing says inspiring like reminding broke founders that even billionaires cried in the bathroom once.
