The only person who can put you out of business, in the early days, is yourself.

Entrepreneurs can't forecast accurately, because they are trying something fundamentally new. So they will often be laughably behind plan - and on the brink of success.

The mistake isn't releasing something bad. The mistake is to launch it and get PR people involved. You don't want people to start amping up expectations for an early version of your product. The best entrepreneurship happens in low-stakes environments where no one is paying attention, like Mark Zuckerberg's dorm room at Harvard.

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.

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

You know how people always talk about how vision is the key to entrepreneurship and perseverance and really seeing what other people don't see? We can actually redeem a fair amount of that folk wisdom.

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.
