Brooke’s podcast process

I’d love to know Brooke’s process for her podcast – how far in advance she plans the topics, and especially how she keeps her notes to make the podcast sound so smooth. Is it just a list of topics to hit, or something more? In a few of the podcasts I’d heard you can tell she’s reading, but in later ones it’s very fluid. I know that everyone finds their own methods, but learning about one’s mentor’s methods is really helpful as well. Would also love to know what other kind of prep she does other than presumably making notes on things to hit on. Thanks!
