If you want absolute perfection it takes practice so if you are bored with the practice you might be better off making small projects to use up your stash? Try table runners and bed runners, place mats, mug rugs and bags. If that fails, perhaps your interests just lie elsewhere, and there is no shame in that as everyone has different likes. Perhaps you just haven't found your niche?
One thought is that you may gain new motivation if you were prepared to show a younger person the basics?
