I did this kind of work last summer, but with a slightly different spin. Since I was having trouble with the whole "make a list thing", I quickly tore through 10-12 magazines and pulled out all the pictures that looked to me like "it". Then I went through that pile of pictures and picked my favorites. Then I taped those pictures to a piece of paper and wrote underneath each one what character trait they represented.
In the end I had one sheet that said "Him" and included things like intelligence, humor, dorky, compassionate; one sheet that said "Who I am for him" that included smart and sexy; and one sheet that said "Who we are for each other" which included mutually empowering and committed to raising a family. I didn't spend a lot of time on it. I did it without thinking, as much as possible, because thinking only seemed get me stopped or stuck. Then I stuck the whole thing in a drawer, convinced it was entirely silly, but still holding onto some sense that perhaps I was beginning to cause something.
And guess who showed up a month later?
