If you are this frustrated, I would suggest you purchase a couple of stencils of designs that you want to learn. Practice with them enough and you will develop muscle memory. You can purchase stipple and meander patterns, as well as anything you probably ever dreamed of. I just don't enjoy following a line, so I practice A LOT!
Here are some free pantographs that you can practice with. Just print them with your printer.
