Hi and welcome! In addition to the advice of keep practicing, I'd add this. Don't expect to be perfect in a few days. You'll make mistakes, but time and experience will teach you how to correct them. Be willing to experiment with needles, yarns, patterns etc. A scarf is excellent for a first project. Dishcloths are also nice. I'm making a lot of them for Christmas gifts.
Anyway, welcome to the world of all-consuming addiction. I crochet as well, and thankfully we don't have to choose. You really can have it all!
