I would have changed the focus from sales and marketing to delighting customers earlier, as our early DNA was too sales-heavy and not customer-focused.

We didn't compromise on making things easy, and because I relied on a foundation of principles, it was scalable to the largest applications on the internet.

Every time we have a big idea about the future, we need to be mindful of how to meet people where they are today and incrementally bring them to the promised land.

When we started, there was no grand strategy; it was bottoms up from users in the early days, and we were able to make a dent because many competitors were building supply chain backward instead of customer backward.

I had to balance transparency with kindness when discussing the company's future with my team, especially as we grew larger.

We need to be mindful of how to meet people where they are today and incrementally bring them to the promised land.

In the early years at Facebook, we should have focused on iteration speed rather than building a large team and a polished product.

We stumbled into something people really wanted, which led to growth, even though we initially didn't understand what was driving it.

I'm constantly looking for gaps between what we could be doing if we were following the principles and what we are doing.
