The lean startup method is not about cost, it is about speed.

A solid process lays the foundation for a healthy culture, one where ideas are evaluated by merit and not by job title.

Lean thinking defines value as providing benefit to the customer; anything else is waste.

Entrepreneurship is not really building a product, it's not having an idea, it's not being in the right place at the right time. It's fundamentally company building.

If you can’t out iterate someone who is trying to copy you, you’re toast anyway.

The only way to win is to learn faster than anyone else.

I would say, as an entrepreneur everything you do - every action you take in product development, in marketing, every conversation you have, everything you do - is an experiment. If you can conceptualize your work not as building features, not as launching campaigns, but as running experiments, you can get radically more done with less effort.
