Recommend going through @trengriffin threads on cash flow on twitter. Here’s one of his threads on cash flow. https://twitter.com/trengriffin/status/1335419820569841664
Also, I’m planning on going through Michael Mauboussin’s online tutorial.

It’s a companion to his book Expectations Investing. I’m planning on doing these tutorials and then reading his book, which is supposed to have a new edition soon.
