Podcast Ideas

I really want my podcast to be interesting, but I can't decide on what it should be about. I really can't decide. I'm thinking of just telling a story about possibly an injury I sustained or something traumatic, but entertaining that has happened to me. However, when I try to think of an example I come up blank. It's annoying because I know there are plenty of examples, I just can't think of them when I need to. Hmm, maybe I'll just talk about a collection of short, random stories from various times in my life. 3-5 minutes is a tough length to work with because once I get started I might have trouble wrapping it up.
