Social status used to come from owning things like cars and watches. Now it comes from experiences you post online. The speaker calls this "diffty": doing things mainly to share them and build your personal brand.
Status update is the new status symbol. What does that mean? It means in the 80s 90s, early 2000s, people would build their brands by cars, watches, houses and sneakers. It was the brands that were social currency. They would buy this stuff as a way to represent who they are to the world. But now experiences are a new social currency. If you think about it, before Instagram, if you went on an amazing trip, snuck down to the front row, traveled to a far amazing place, the only way that you could share that was actually showing people your photo album, right? But now you could share it at scale. Experiences are what people are pursuing, which is driving a whole new trend which I talk about in my book Youth Nation, called diffty, which stands for did it for the Instagram, which means that experiences are so important at building one's personal brand that they actually pursue it, not even so much to enjoy it, but to prove to everybody that they were there.
