Please do not give up. As has been said, practice is the answer. Doodle on paper and make up some some quilt sandwiches to practice on your machine. The concept of moving the sandwich and keeping the needle in one place is in opposition to how we draw or write which is to keep the paper still and move the pencil. Once you think about that as you are quilting (with some nice music on to relax you), I think you'll find satisfaction in what you are doing.
