I think we have to model 21st century workplaces. In fact, the Manning Institute commissioned a survey a number of years ago. They interviewed female community leaders, mid-level professionals in their late thirties to late fifties. Women did not say they didn't want to run because of a lack of interest. They said that, in fact, they did not feel the environment would be one where they could immediately make a difference.
There is a misperception about politics: what does it mean to actually be in the political space and make a difference? But also women were not feeling compelled to leave successful professions because they misunderstood or misread what the opportunity was.
I think systems-level changes are really important, but I also think proactive mentorship is as well. I'll leave it to Eleni, as someone who has served.
