Learning to see waste and systematically eliminate it has allowed lean companies such as Toyota to dominate entire industries. Lean thinking defines value as 'providing benefit to the customer'; anything else is waste.

Entrepreneurs always pitch their idea as 'the X of Y', so this is going to be 'the Microsoft of food.' And yet disruptive innovations usually don't have that character. Most of the time, if something seems like a good idea, it probably isn't.

The problem with entrepreneurship is we are often working really hard producing high quality products that no-one wants. The creation of stuff is not valued.

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.
