Fascinating interviews. Lot's of useful tips for business and life. It's a bit of a gamble because this style of seminar does not have a clear curriculum (e.g. it's not "how to edit photographs in Photoshop").
I would say that if you have found Tim Ferris interesting and useful in the past (e.g. books, articles, talks) then you will enjoy and find this seminar useful. Try listening to the free portion and see whether it resonates with you.
