I've picked up so many mental models from these podcasts. I constantly refer to things I've learned over the years from these fantastic shows:

• 99% Invisible: design in everyday life

• Akimbo (by Seth Godin): incredible wisdom on business and design

• The Anthropocene Reviewed (by John Green): deeply human musings

• Articles of Interest: histories of fashion and social convention

• Conversations with Tyler: deep conversations

Some of them are listener-supported, so consider donating :)
