I don't understand how people here are recommending Zero to One and Lean Startup at the same time. They contradict each other. And in fact the Lean Startup is full of the kind of foolish post dotcom-crash thinking that Zero to One warns against.
The test of a first-rate intelligence is the ability to hold two opposing ideas in mind at the same time and still retain the ability to function. - Scott Fitzgerald
I disagree that the two ideas are completely opposed. They both describe tools in building something. Though if I think about how Zero to One is approached, I feel it's more of a manifesto on overcoming challenges, and doing challenging things. Lean Startup focuses on how to run small experiments.
Nobody says building something challenging isn't just the process of running lots of experiments to find what works.
