I really enjoyed this very readable book by Janet Kestin and Nancy Vonk, who rose up through the ranks of the ad biz and for years were the co-CCOs of Ogilvy and Mather Toronto. They wrote with warmth, humor, and frankness about what it took to do that as women and moms.
I was left with no desire to work for an ad agency (I think it was the part where they talked about reclaiming their Sunday evenings -- I frankly can't work weekends and still be productive), but it's always been a life I've been curious about, since it does seem like the most fun environment to be a copywriter in.
The stories are great. For example, about halfway through, they describe the Diamond Shreddies ad campaign (watch Rory Sutherland's TED talk, "Confessions of an Advertising Man," if you don't know what that is). But the lessons probably apply outside of advertising, outside of art directors and copywriters.
My only complaint is that it's hard to tell who's writing at any time. I think Janet is the one who says she's always been outspoken, so it took her a pretty in-your-face moment to realize the sexism that was all around her. And I think Nancy is the one who said she was always embarrassed to ask for a raise until a woman colleague took her aside and said, "You're always complaining about being broke. What do you make?" and then informed her she was underpaid. More importantly, the woman pulled out a notebook from her desk, and read from it her list of ammo: wins she had had, successes she had contributed to. Those were the things she used to ask for more money, and she told Nancy to do the same.
