Using the Product Development Waterfall diagram for Customer Development activities is like using a clock to tell the temperature. They both measure something, but not the thing you wanted.

In a startup no facts exist inside the building, only opinions.

The core tenant of what I teach is there are no facts inside the building. When we come up with a new idea, we tend to slide into our own reality distortion field to convince ourselves and others. And that's not healthy.

Essentials of how to do a startup do not include writing a business plan

Startups don’t fail because they lack a product they fail because they lack customers and a profitable business model.

There are no facts inside the building so get the hell outside.

For students to understand what the future of journalism is going to be, they're going to have to invent it. It's a big idea. We don't know what journalism is going to look like in the next three years, let alone the next 10 years.

The world is run by those who show up not those who wait to be asked.

You need to ask yourself, ‘Where do you want to work: startups, mid-size or large companies?’ If you find yourself debating the ‘startup versus large company’ choice you’ve already chosen the big company. Entrepreneurship isn’t a career choice it’s a passion and obsession.

Unless you have tested the assumptions in your business model first, outside the building, your business plan is just creative writing.

A startup is a temporary organization designed to search for a repeatable and scalable business model.

People talk about getting lucky breaks in their careers. I’m living proof that the “lucky breaks” theory is simply wrong. You get to make your own luck... The world is run by those who show up…not those who wait to be asked.

Disruption on the first day always looks like a toy.
