Crochet

Hey there! I did some little projects of 30-45min and my wrist felt a bit sore at the end. While I understand that me being new to thoses movements and may still be a bit crisp, I was wondering if there is some absolute don't hold your tool or yarn like that to avoid hurting myself. For now, I use my thumb to slide the yarn on my hook and both my hands (alternate) to hold my project. I see a lot of yarn around index and project holding between thumb and middle finger and it doesn't feel stable alenough for me. Should I try again or just de what feels comfortable (even if it's slower)?
