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

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.

Those words are from Lynda Barry's novel 'Cruddy.' I've carried them with me for some time. There's a lot in my life I wasn't expecting. One is the realization that I stood at this pulpit and delivered a reading for my own graduation...15 years ago. Unexpectedly, I'm old.

Everyone has an idea, but it's really about executing the idea and attracting other people to help you with the idea.

All my days are themed. Monday is managementTuesday is product, engineering, and design. Wednesday is marketing, growth, and communications. Thursday is partnership and developers. Friday is company and cultureOn the days beginning with T, I start at Twitter in the morning, then go to Square in the afternoon. Sundays are for strategySaturday is a day off.

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.

Meet customers where they are; question how to make the tools customers use more valuable.
