Is this you? Do you want to get behind the microphone, but aren't sure what kind of podcast you want to have?
Do you even need a topic, or can you get behind the microphone and start a podcast about "anything and everything"? The reason I put that in quotes is because plenty of podcasts use that phrase to describe themselves. I'm not saying it's a bad thing, either. I listen to plenty of comedy podcasts that use that exact phrase.
But I will recommend if you're thinking of using a podcast to boost your brand or business, maybe the "anything and everything" route isn't for you.
