My mother used to say I was a true Gemini - because I could never do just one thing at a time. I have since decided as easily distracted as I am that it was ADD all along. It's been so long that I have finished a quilt without interruption I am not sure if I ever have. When I am putting blocks together I do usually put it together and not piecemeal it. It's the satisfaction of finishing something that keeps me going. (I may need to make 150 blocks but making one at a time works for me. So when I get a 1/10th done, then 20%, etc.) It's a mind game - but it works for me.
