Honestly, my friend tried learning from a book and got totally stuck on one step. Then she watched a video where the person messed up the same part and had to redo it. Seeing that normal mistake is what finally made it click for her.

Seen the same thing happen with gluten-free and keto stuff a few years back. Suddenly every product slapped that label on and jacked up the price, regardless of actual need. Just chasing a trend for quick money.
