Making something simple is very difficult.

What I love about New York is just the electricity I feel right away.

Twitter was around communication and visualizing what was happening in the world in real-time. Square was allowing everyone to accept the form of payment people have in their pocket today, which is a credit card.

You don't have to start from scratch to have a massive impact on the world.

My goal is to simplify complexity. I just want to build stuff that really simplifies our base human interaction.

Success is never accidental.

A number of people in the United States, almost everyone, is using plastic cards to pay for things, but it's extremely difficult to accept these cards. So let's make it's easy and take more and more of the friction out as we can.
