Before you start your podcast, you should decide what will be the overall theme for your show.
If you have a business, and you’re using your podcast to promote your business, then it makes sense to create a podcast based on what you do in your business.
If you’re a Coach or Consultant, whatever it is you do to help your clients, this should be what your podcast is about. This way your listeners can get a taste of what you do and will want to know more.
