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

Build what you want to see in the world.

You don't have to start from scratch to do something interesting. You don't have to start from scratch to have a massive impact on the world. You have to have a good idea. You have to convince other people of those good ideas. And you have to push as quickly as possible.

As CEO, my main job is editor-in-chief.
