Be sure to make a folder for all the “assets” you’ll use for your episode. It’s a good idea to make subfolders too: Narration, Interviews, Active Sound, Ambient Sound, etc. Once you take a sound file and load it into Audacity, be sure not to move it from the folder it’s in.

You should name your files so you’ll recognize them, like such:

Intro New Lady Narration
Intro Music bed Sunny Day
Segment 1 Arrival narration
Segment 1 Ambient sound: chirps and clucks
Segment 2 Sound Effect Alarm
Segment 2 Narration
Segment 2 Active Sound New Lady Screech
