Don't settle. Experimenting with new episode structures, equipment or production techniques can bring fresh perspectives to your podcast.
For instance, Build a Big Podcast now features new cover art as part of this evolution process. Will I keep it? Who knows? Cover art, like anything, is always a work in progress.
The changes you make don't have to be obvious on the outside. For example, I recently changed up the way I edit podcasts. And the way I schedule guests.
Complacency hinders progress – that's the big idea. And if something doesn't work, you can always go back to what you were doing before.
