I struggled with magic circle until I started pulling my right needle completely through so that it had no stitches on and going into the working stitch, rather than pulling the loop through the middle of the work
I really like Norman from Nimble Needles. He has a blog and a YouTube channel with lots of tips on many different knitting topics. Remember that circular needles are a good investment because you can use them to knit flat, too. Even better if they are an Interchangeable set!
