Ask HN: Do podcasts focused on happiness/productivity seem least happy to you?

I've noticed the productivity/zaney/optimise your life/what is happiness type podcasts seem to have a lot of seriousness and not so much enjoyment.

What I find recently annoying is how each guest will give totally different advice on say longevity or happiness to the last guest, and the host will still keep a ":O" face and say it's amazing. Even though it contradicts the advice they were head-over-heals for last week...

What's going on? Do these podcasts give you an eerily off feeling, as compared to the "kick some beers/two dudes talking" podcasts?
