Because startups often accidentally build something nobody wants, it doesn’t matter much if they do it on time and on budget. The goal of a startup is to figure out the right thing to build - the thing customers want and will pay for - as quickly as possible.

Learning is the essential unit of progress for startups.

If your goal is to make money, becoming an entrepreneur is a sucker's bet. Sure, some entrepreneurs make a lot of money, but if you calculate the amount of stress-inducing work and time it takes and multiply that by the low likelihood of success and eventual payoff, it is not a great way to get rich.

We need to reengineer companies to focus on figuring out who the customer is, what's the market and what kind of product you should build.

Meritocracy is a good thing. Whenever possibly, people should be judged based on their work and results, not superficial qualities.

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.

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