That's really great advice, i think that's kinda the spot i'm in at the moment, personal friends haven't been interested and well i just kinda feel stuck as i feel a one person podcast wouldn't be too entertaining.
I dont listen to as many podcasts as I used to, but I listened to quite a few football ones during the season that was just one person. The biggest advice I can give you as a novice listener is to just remember to have fun. Be the biggest version of yourself that you can be, and really let the listener feel your passion. The listener can tell if you really care about something, or if you're just saying it hoping it brings about more fans. Be true to how you feel and love, and you'll be solid.
PS this comes from a guy who has never attempted to do anything like this, so I could be 120% wrong. lolol. Just my 2 cents.
