I used to listen to Tim Ferris years ago, even bought the 4 hour workweek but for whatever reason I eventually lost interest. I think he was a bit predictable and bland also a bit too deep into "Tech" culture.

Never really paid much attention to Sam Harris so might have another look at him.

One of the most interesting things about Joe Rogan is that he's not a one trick pony e.g. Comedy/Fighters/TV personality etc. I find him more interesting as a result.
