Those who have been crocheting 10+ years, how did you learn?

And what are the main mistakes you see beginners making? When I started crocheting using the Woobles about 7 months ago, the instructions clearly said the way to face your hook at each stage of the stitch (ex. face the hook down and turn it up when pulling up a loop) but I noticed tonight I somehow have gotten sloppy with what I’ve learned and it shows because I’m constantly having to stop and put my yarn back on the hook.

What are some mistakes y’all veterans see often?
