Can you learn English by listening (podcast)? (YouTube, Spotify)

I’ve recently started doing a podcast on the topic of films/film reviews. I personally enjoy it and personally don’t think it’s as bad as I do (without wanting to praise myself now)

I only do it as a hobby and don’t want to invest a lot of time now.

I’ve also had some positive feedback.

But really many people aren’t listening to my podcast now, sometimes only 1-2 people.

Do you think it’s stupid/ridiculous/etc if I continue anyway, simply because I enjoy it, listen to it regularly and a few listeners over time.
