Hi @kristen4,
I’ve looked into passive income a few times over the years and every time I do I end up seeing exactly what Megan said- most sources of passive income aren’t actually all that passive, most especially when you’re trying to set them up. I haven’t had any luck yet- so I’ll be watching along this thread and soaking up everyone’s words of wisdom too! 
That’s an awesome goal to have, Kristen! 
Definitely take Megan’s advice, as she has her own magickal site and shop set up that are amazing. There are numerous other talented businessfolk around the forum too (forgive me, I can’t possibly tag everyone here- but many are listed in the Coven Member Shops- feel free to take a look for inspiration!) so it definitely can be done 
A shop probably wouldn’t be very passive to manage, though- but a blog or review site would become mostly passive once you set up enough content 
Wishing you all the best and cheering for you, Kristen- keep us updated on your progress! You can make this dream of yours a reality
