As Andy said, it depends on what your goals are, but I listened to 90%+ of the podcasts before even joining the site and they were the missing link for me to get started on actually directly tackling my dating problems. So I'll link my personal favorites:
https://castbox.fm/vb/398895418 - (get out on the front lines) - by far the biggest one. not the first one I heard but the one that got me to just go out to where I could approach and imagine myself doing it
https://castbox.fm/vb/410364570 - (shit day? rewrite the story) - used to tell myself this a lot early on, when i felt i had a shit day in the past, I'd just give up and do nothing (or shit week). probably listened to this one 5+ times. at first I used to tell myself this directly as a deliberate thought but now my mindset has transformed to decoupling prior events from actually taking action now (iow, who cares what happened earlier, just do something now).
https://castbox.fm/vb/405763144 and https://castbox.fm/vb/380406312 - (stop being afraid of your masculinity / don't be guilty for your desires as a man) - never felt i was masculine, and i still struggle with this, but this one at least made me stop feeling guilty for being a man (because i used to think liking girls and wanting to fuck them was something i should be ashamed of)
https://castbox.fm/vb/403563903 - (you will never feel ready) - i used to try to make sure "everything was in place" before starting to learn something new. this podcast probably helped me start approaching in a small town with totally shit volume instead of trying to sort out moving to another place and *then* starting.
https://castbox.fm/vb/368374216 - (why i advocate honesty) - this one made me realize i was a compulsive liar and i ended up writing a huge personal journal about it one day in the park and breaking down why that was so. won't get into the details of my personal issue here but this podcast helped me realize it's objectively better to be honest.
Also a note about time and listening to the podcasts. I didn't have a lot of random free time either, I just listened to a bunch on autoplay while I was driving, ironing my clothes, cleaning my room, etc, and eventually before I was going out and trying to approach as motivation. I spent about 1+ months listening to them randomly (without having some preconceived "goal" of listening to all of them). I just enjoyed listening to them. 365+ podcasts can be intimidating if you make it some big deal to listen to them, but you can just fit it throughout your day.
