Vanity metrics are the numbers you want to publish on TechCrunch to make your competitors feel bad.

The grim reality is that most start-ups fail. Most new products are not successful. Yet the story of perseverance, creative genius, and hard work persists.

In a startup, both the problem and solution are unknown.

Most phenomenal startup teams create businesses that ultimately fail. Why? They built something that nobody wanted.

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

We must learn what customers really want, not what they say they want or what we think they should want.

Don’t be in a rush to get big. Be in a rush to have a great product.
