This inter­view between Tim Fer­riss and Derek Sivers—the entre­pre­neur who founded CD Baby—concentrates on The 4-Hour Work­week and pro­vides a good recap and overview of the con­cepts. The fol­low­ing quote, how­ever, feels more rel­e­vant to me now as it was when I orig­i­nally read the book:

To learn any­thing quickly, I approach peo­ple who did it cor­rectly and say, “I have an idea, but I don’t know any­thing, so can I buy you a beer and pick your brain? I’m really ambi­tious but kind of igno­rant.” Whether it’s lan­guage learn­ing or tango or kick­box­ing. That’s how I did all of it. That’s how I iden­ti­fied the rules of engage­ments, so I could decon­struct them.
