My mom cares that I tweeted a picture of my breakfast. She's knows I'm eating and I'm safe.

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.

Amazing what people make up based on what they choose to see.

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

The greatest lesson that I learned in all of this is that you have to start. Start now, start here, and start small. Keep it Simple.

The idea of Twitter started with me working in dispatch since I was 15 years old, where taxi cabs or firetrucks would broadcast where they were and what they were doing.

Build what you want to see in the world.
