JanRN I hope you are not getting yourself bogged down in "must do's" I find what works for me and that is to work in small increments of time. I will set the timer on my oven, cause I don't always look at my watch, for an hour and then tell myself that I am going to get xyz finished in an hour. If I don't get it all finished I don't beat myself up just adjust my capabilities.
When I was trying to get Jamestown finished and it seemed to be dragging me down a little, I would sew a row on and walk away, chat on the computer, clean my kitchen, read a patchwork book, whatever, then go back and sew another row on, if you want to start something new make it small enough that you can finish it in a few hours or days and see results. Then you may have the motivation to do a few more PC rows.
Good luck
QNS I am popping into the RV for a coffee and some yummy cookies, hope you have some left
