What if becoming wildly successful didn’t feel the way you thought it would?
Lucy Guo became the youngest self-made female billionaire in the world — but what she learned about money, ambition, and identity might surprise you. As a co-founder of Scale AI she (an AI unicorn) she shares her thoughts on AI and how to best prepare yourself for what is coming.
In this episode, we talk about what it actually takes to build something at the highest level, why money doesn’t solve the problems you think it will, and how your environment, network, and willingness to take risks shape everything.
Lucy shares the realities behind building billion-dollar companies, the pressure that comes with success, and why some of the most important decisions have nothing to do with intelligence — and everything to do with how you think.
If you’ve ever felt behind, questioned your path, or wondered what it really takes to “make it,” this episode will change how you see success.
