The Rich Roll podcast is a great one. Literally every time I think it's gonna be too out there in terms of hippy craziness it blows my mind with some bits of wisdom. Crazy variety of guests and a very positive message. One day it'll be a guy that travelled the US by bike, the next a CEO who dropped out of the game to teach meditation and the next a triathlete doing 50 ironmans in 50 days and so on.
