I don't think there's a person here who's made a quilt without running into any sort of trouble. Sometimes we don't get the fabric we want, the color scheme is wrong, have to deviate from the original idea, we cut the pieces all wrong, our seams and points don't quite match up, our blocks aren't square, can't get the layers of the quilt straight, the quilting snags in the machine, our thread breaks, the binding gets wavy, or something else doesn't quite go right. Sometimes we have doubts our ideas and think "they're gonna say I'm crazy!". Some of us have made an "ugly quilt" where we think everything is wrong with it. But we sure don't quit.
You sound like you're meant to be a quilter. You want to try and keep going at it even though you wonder if you're really meant to be a quilter. To quote the drummer from my favorite band (though she was giving advice to people wanting to learn the drums, this could apply here as well): "Practice because you're not going to get it on the first try".
