What will be your hook? The thing that makes you different from every other example of people trying to FIRE?
If you are going to do interviews, how will you differentiate them from the interviews on the Choose FI podcast?
How are you planning to engage a younger audience, since this will likely be the population your story most appeals to? Will you just make a podcast, or will you have more of a social media presence, like instagram and TikTok?
A fresh take might be something akin to reaction videos to consumerist trends, this is a great way to capture a current Zeitgeist from a different perspective.
For example, I keep seeing stuff about Shein Hauls, this is apparently a trend where influencers order ginormous orders of fast fashion clothing from Shein and then model how ugly the bulk of them turn out and the rare bits that are actually good.
It's heinously wasteful, but the videos are popular, so a frugality/minimalist reaction to something like that could be a fresh take on a really tired narrative.
