I spend 90% of my time with people who don't report to me, which also allows for serendipity, since I'm walking around the office all the time. You don't have to schedule serendipity. It just happens.

Twitter is the world.

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.

An idea that can change the course of the company can come from anywhere.

'Luck' is recognizing when the situation encourages build out and execution.
