[Mark Bertolini](https://en.wikipedia.org/wiki/Mark%5FBertolini?ref=kudithipudi.org) in a chat with [Patrick O’Shaughnessy](https://x.com/patrick%5Foshag?ref=kudithipudi.org) on “[Invest Like the Best](https://joincolossus.com/episode/performance-during-pain/?ref=kudithipudi.org)” podcast, speaking about the need to update your mental model about the world constantly. And the two things that differentiate good leaders from the rest.

> I always say to people, the mental model that exists inside your head about how the world works is the most critical tool you have. And if you **don’t constantly add new information** to it and are not a continual learner, **you can’t possibly know what you need to know to make good decisions**.  
>  
> And so I look for two things in executives, **curiosity and courage**. **The curiosity to continue to ask questions and learn more every day, and the courage to act on it when you have a hypothesis that might be powerful**.
