Careers in advertising are long and hard. (That’s what she said.) To coincide with this year’s 3% Conference, we launched thatswhat3said.com, a place where women in advertising can give advice to female creatives who are just starting out. (We considered calling it “Women on Women,” but we’re far too mature for that.) Visit the site, share it widely, and add to it. Your wisdom, warnings, and legends could help a young, shiny creative hold on to her optimism as she runs the ad biz gauntlet.
