Excerpts from the new book on Y Combinator.

I wish more startups would pay more attention to this advice from Dropbox Dude:

Two days before, at the dinner, Drew Houston, the founder of Dropbox—summer of 2007— had been the guest speaker. Afterward, he told Paul Graham there was something else he had intended to say about successful startups but hadn’t gotten to: “They don’t fuck around, right? The startups that succeed, they don’t go to meet-ups, they don’t run around talking to boards of advisers, they just write code and talk to customers, right?” This is Graham’s oft-repeated mantra, too. Write code and talk to customers.

Startups that succeed just write code and talk to customers.

how does one write code? how does one talk to customers?

You write code one line at a time.

You talk with customers one person at a time.

Little by little, step by step, every day.
