I believe for the first time in history, entrepreneurship is now a viable career.

Except in very narrow cases, where there's breakthrough science that needs patent production, worrying about competitors is a waste of time. If you can't out iterate someone who is trying to copy you, you're toast anyway.

What if we found ourselves building something that nobody wanted? In that case what did it matter if we did it on time and on budget?

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.

The hardest part is the grueling work of constantly being wrong.

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

Leadership requires creating conditions that enable employees to do the kinds of experimentation that entrepreneurship requires.
