The mistake isn't releasing something bad. The mistake is to launch it and get PR people involved. You don't want people to start amping up expectations for an early version of your product. The best entrepreneurship happens in low-stakes environments where no one is paying attention, like Mark Zuckerberg's dorm room at Harvard.

Don’t be in a rush to get big. Be in a rush to have a great product.

If the plan is to see what happens, a team is guaranteed to succeed - at seeing what happens - but won't necessarily gain validated learning - If you cannot fail, you cannot learn.

The Lean Startup has evolved into a movement that is having a significant impact on how companies are built, funded and scaled.

The way forward is to learn to see every startup in any industry as a grand experiment.
