I'm with you. I seem to "unsew" (rip stitches) as much as I sew lately. I, too, feel more self-imposed pressure on myself because I know more about how it's supposed to be than I did when I started. I'm by no means a perfectionist, and I don't take quilts to shows that give ribbons or critique my work. It's far from perfect, but I am learning so much with each one I make. (A lot of, don't do it like that next time!)
