You can access a review of the key points from the Zero to One book by Peter Thiel here. In particular have a look at these four statements of what he has observed:
- It is better to risk boldness than triviality
- A bad plan is better than no plan
- Competitive markets destroy profits
- Sales matter just as much as product.
His conclusion here is that we need to be careful about broad brush conclusions reached as a result of mistakes like the dot-com crash. Instead he says that: “to build the next generation of companies, we must abandon the dogmas created after the crash … the most contrarian thing of all is not to oppose the crowd but to think for yourself”.
