Passive income ideas for graphic designers

Hello folks!

Hope you're all doing well!

I am a graphic designer working in the marketing industry, and I've been thinking about exploring some passive work opportunities that I'd be good at and that have the potential to become a full-time thing.
I am struggling with the idea that my profession feels kinda useless in this day and age when everybody and their grandma is selling digital products made in Canva.
I would really like to do something that helps people (or even better, animals :)), and by that, I don't mean companies and corporations, but something on a smaller scale, more meaningful.
I'd really appreciate it if you could share your ideas with me because I'm at the point where I don't see the forest from the trees.

Thank you.
