For some the twenties are a fun, relatively carefree time (who are these people?), but for many women this decade is stressful. They’re trying to work out how they fit into the workplace, whether they’re even in the right career, and how to communicate with older colleagues. The world is far more competitive than it was 20-plus years ago when I started working. But that’s not the only thing that’s different about the old me and today’s twenty-somethings.
