Set small goals. Instead of thinking to yourself...I really need to finish that quilt! Be more specific. Add the next step to your to do list for the day. Instead of feeling overwhelmed by an entire quilt, it seems much more managable to "Make 5 Blocks" or "Cut the background pieces" or "Sew one row together". If you get more done, fantastic! If not, at least you will be one step closer to having that quilt finished, but instead of guilt, you can feel a sense of accomplishment. Now go get the next step done on whatever it is you are working on!
Enjoy every stitch!
