Each week the NZ Herald and Newstalk ZB's Cooking The Books podcast tackles a different money problem. Today, it's what some say you need saved to achieve early retirement. Hosted by Frances Cook.

It doesn't matter how much you like your job, you're there to get paid. That's what makes it a job, rather than a volunteer role.

We've mentioned on this show before about the FIRE crowd, meaning Financial Independence, Retire Early.
