Courses, Books...?

Hey everyone,

A few months ago, I started in the world of magic, specifically card magic. I picked up the card worker's bible (Cartomagia fundamental) and started practicing, reading and re-reading the initial chapters (which included self-working and semi-automatic tricks). A few days ago, I paid for a course from a pretty well-known magician on TikTok (not sure if I should name names, so I'll play it safe and won't). The course is pretty good, actually. However, for me, I'm looking for more theory (techniques, moves, etc.).

So, here's my question, and I'm hoping for some wise magic advice: What would be a good next step to keep progressing in magic and avoid hitting a plateau?

There are thousands of tutorials and tricks on YouTube, and plenty of books out there too...

All the best!
