On marketing: "In the old world， you devoted 30% of your time to building a great service and 70% of your time to shouting about it. In the new world， that inverts."
On pivoting: "If you're not stubborn， you'll give up on experiments too soon. And if you're not flexible， you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve."
