How do you hone your craft on an everyday basis? It could be writing, meeting with experts, even listening to podcasts, just so long, argues economist and blogger Tyler Cowen, as it makes you better at what you already do. Perhaps more than anything else, he believes, it's practice that divides middle managers from founders, and mere good hires from the creative obsessives who end up transforming the world. Join Cowen and EconTalk host Russ Roberts for a conversation about Talent, Cowen's new book on how (and how not) to identify the talented. Hear Cowen explain why, for high-level positions, unstructured interviews are important, why stamina is usually preferable to grit, and why credentials are largely a relic of the past.
