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

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.

Every startup has a chance to change the world, by bringing not just a new product, but an entirely new institution into existence.

There is much that public policy can do to support American entrepreneurs. Health insurance reform will make it easier for entrepreneurs to take a chance on a new business without putting their family's health at risk. Tort reform will make it easier to take prudent risks on new products in a number of sectors.

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.

The lesson of the MVP is that any additional work beyond what was required to start learning is waste, no matter how important it might have seemed at the time.

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