A few podcasts: Joe Rogan, Tim Ferris, and The Art of Manliness. Mainly because they interview a lot of different people. I skip a lot, but it exposes me to a bunch of new books and things. I listen to other podcasts, but they're normally directed to specific areas.

The one that's clicked with me the most: Sebastian Junger on JRE[0]. I still need to read Tribe, but listening to Junger discuss it really aligns with me, as someone who has transitioned out of the military in the last few years.

I'd say, the Bible has been most useful for me. But it took about 10 years since I first read it, for the lessons to really click.

Good luck, and please share what you come up with.

Me too

Naval Ravikant

He's done 2 periscopes (@naval)and there is a 2 hour podcast with him on farnam street that are all amazing and don't overlap too much.

Second Naval Ravikant. He's a deep thinker and his twitter is a goldmine.

Naval represents an enticing mix of viewpoints of spiritual guru, contrarian jester and visionary technologist.

Here are some of his best quotes

Absolutely. Listening to him is akin to having a high fidelity source of illumination shining right at you.

Yourself.

Your own thoughts, journal, thinking about your thinking, thinking about behaviour, self-reflection, thinking about others,figuring out your purpose, figuring out your values

Several good mentions here already.

Recently been getting into High Performance Habits by Brendon Burchard.

For personal growth within the context of becoming better in the tech field, I enjoy the Developer Tea podcast.

I also have enjoyed the Meta Learn podcast and from time to time select episodes of Tim Ferris.

Me, myself and I
