There are a few different things. I think your example of making sure that young women see leaders in action is critical, because the saying that you can't be it unless you see it is I think very true for women. You have to have the role models and see them to know what is possible. That's the first thing, which I think is critical.
Another important piece of advice is that what got you here won't get you there. You may have had strategies that got you to a certain level of success, but if you're ambitious and want to get to the next level, you're going to need to develop new strategies. We heard that culture in the workplace is important. If you think about the example we heard in regard to non-traditional roles for women in construction and the trades, you need to be able to move successfully in that kind of culture, so you have to seek out the new skills that you need.
That's where I think mentorship is very important. It allows you to talk to someone who is invested in your career, but in an impartial way, if you will. They are perhaps willing to call you out, nudge you in some ways, and sometimes just be a great sounding board.
