Hah! Try being married to one! I love him dearly, but he simply can not focus on more than one thing at a time, and that focus is
always given to whatever seems the most fun. He loves the idea of the end result, just not what it takes to get there UNLESS it's super duper important to him. He probably would have done better with a stronger J who actually
likes being in charge of everything menial and dull, but, oh well. I love him anyway.
Oh, and to answer the Op: I've found screaming and throwing things to be a great temporary fix to get things done! And holding sex out like a carrot, but that doesn't really apply in your case...
