The speaker's grandmother asked him daily: what do you know today that you didn't know yesterday? He argues this simple question builds a growth mindset that matters more than any product you make. Modern tools make learning faster, so the real work is asking yourself what you learned each night.
What do you know? This is like quite grandmother's question to us kids. Whenever she would see us, she would come into the room, we'd give her a hug, and she would say, what do you know? What do you know today that you didn't know yesterday? What is true today that wasn't true yesterday? That question of what do you know pushes you to have growth in your head that is going to be far more important really than any artifact you create. The opportunity of using these tools is that you get to grow much faster because of the reduced friction in the turn of that wheel, as we all create new artifacts and, and get to explore new domains. So at the end of each day, ask yourself, what do you know that you didn't know at the beginning?
