James Cameron has spent four decades operating where politics, business and the environment collide. He helped shape modern international climate law, advised governments across the world, founded one of the first climate investment businesses to manage over $1.7 billion, and still believes the biggest opportunities are ahead of us.

But this conversation isn't really about climate.

It's about reinvention. About being expelled from school twice before becoming one of the world's leading legal minds. About why great ideas rarely progress in a straight line. Why optimism is a competitive advantage. And why the people who build the future are usually the ones naïve enough to believe impossible things can be done.
