An excellent point bigbrownowl!!! We know ourselves and it's important not to set our goals as to be self-defeating or discouraging.
Another example in myself: I don't set any deadlines at all, as being handicapped, I have to listen to the demands of my body and would find a deadline stressful. I apply that to all my quilting, not just UFOs. I will happily make a quilt for someone's birthday, as long as they understand there is no gurantee WHICH birthday they might get it. LOL. Or which month it might arrive all finished. If I promised something by a certain date, I know I would do all I could to meet that goal and hurt myself in the doing.
So make your goals gentle on yourself!!! Be kind, and allow lots of room for new beginnings and fun projects also.
