dot-com flameouts that erroneously believed that they could lose money on each customer but, as the old joke goes, make it up in volume. - Eric Ries

We do everything wrong: instead of spending years perfecting our technology, we build a minimum viable product, an early product that is terrible, full of bugs and crash-your-computer-yes-really stability problems. Then we ship it to customers way before it’s ready. And we charge money for it. After securing initial customers, we change the product constantly — much too fast by traditional standards — shipping new versions of our product dozens of times every single day.

Think big. Start small. Scale fast.

Most of the time customers don’t know what they want in advance.)
