I ask because I want to start my own podcast, but don't know what I should talk about.
I've started researching the most popular ones (https://www.goodhousekeeping.com/life/entertainment/g28353940/best-podcasts/) and best podcast companies (https://www.betterpods.co/blog/top-podcast-production-companies) to help me.
I'm just stuck on actual topics. I have a wide variety of interests but I'm not an expert at any one thing.
