Make sure you continue to trust what you know now about yourself and stay true to what you believe in

My undergraduate work was in computer science and economics. It just happened to be at that time when 34 percent of computer-science majors were women. We didn't realize it was at the peak at the time.

In the developing world, they don't have smartphones yet. They have the older plastic phones, but women are saving money on those, because they don't have access to banks. Having that access to digital money changes everything for her because she actually doesn't have to negotiate with her husband, which she will tell you is very hard in these circumstances, especially when the means are meager. She's expected to have money to pay for the kids' health or to help with the school fees.

I'm wholehearted about whatever I do.

As a woman finds economic opportunity, even if she's only earning a couple of dollars a day, if she can save it on her phone, she then makes different decisions for her household than her husband might.

If you don't have an effective teacher in front of the classroom, you won't change the trajectory for students.
