There is no greater country on Earth for entrepreneurship than America. In every category, from the high-tech world of Silicon Valley, where I live, to University R&D labs, to countless Main Street small business owners, Americans are taking risks, embracing new ideas and - most importantly - creating jobs.

This is one of the most important lessons of the scientific method: if you cannot fail, you cannot learn.

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

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.

A Start Up is an institution designed to thrive in the soil of extreme uncertainty

In my first start-up, I had an initial advertising budget of $5 per day total. That would buy us 100 clicks per day. At $5 per day, marketing people scoffed and said that is too small to matter. But if you think about it, to an engineer, 100 real humans everyday giving your product a try means you can really start improving.

What differentiates the success stories from the failures is that the successful entrepreneurs had the foresight, the ability, and the tools to discover which parts of their plans were working brilliantly and which were misguided, and adapt their strategies accordingly.
