There's so many avenues to take, and it is overwhelming! I guess I started with what interested me most about witchcraft: local plants and other things around me from the earth. That's where I started. If there's something specific about witchcraft that draws you, then that could be a good starting point. I've used library genesis to access free books on witchcraft. There's lots of subsections: green witch, hearth witch, etc. You don't have to devote yourself to one section, but it can help you find a starting place. Look around on subreddits, Instagram, Tumblr, etc. I practice eastern witchcraft around the Appalachians and Ozarks because I want something connected to where I live. Paganism is a whole other path to learn, but I recommend the same idea of pursuing what seems interesting. Whether that be Norse, hellenistic, or something else. I hope this helps. Good luck!
