Wow... um. It's hard to say, I was surrounded by so many great people --and through books, so many great ideas!
My mom and dad, for sure... but also a couple of very cool aunts and great aunts (one of whom is still gracelessly growing old, she'll be 90 soon!) My elementary school librarian was a big influence on how broad my reading is...which accounts for a lot of the influences in my life over the years.
