Keep your machine set up all the time and steal 5-10 minutes every day. When you need a break from grading grab a few minutes.
When you throw something in the oven grab a few minutes. You may want to add a timer to your sewing room, just in case you get too involved. You deserve to have time for yourself and your quilting. You need not give up something you love to do. Yes, I know that 5-10 minutes doesn't sound like much and the project could last forever...but at least it will get you some you time and someday a new quilt to love.
