He follows his own advice. He presents this idea with a story: a game. It illustrates the idea perfectly.
He presents the idea with his style of humor, with fun special effects, and good visual storytelling.
When he starts the game, he shifts to standing up from sitting down.
I love how he acts out a story within the story. Multiple camera angles and J-cuts make it work. It adds to the video as it’s a “real-life” example of him coming up with the idea and iterating to find the best way to present it.
