Never take your eye off the ball. Always remember that you and everyone on the team is the servant of the cause - in our case, girls' education and young women's leadership in Africa.

For the poor, learning to manage money well is central to improving their lives.

For more than 20 years, Camfed has supported a generation of African girls and women with access to secondary and higher education, employment opportunities, and, ultimately, into positions of leadership.

When I first worked in Zimbabwe, I was a complete novice. I was doing a study, and I continued to learn more and more through the years. And where I have learned most is in the village, from the communities.

I've never argued that humans are massively hot-wired. What I was trying to point out was that you can't understand how we learn unless you identify the learning mechanisms. And these have some genetic basis.

It's not even my job to educate, but what I do is try to facilitate by creating a book that works on different levels. I do want to entertain and bring some joy to the reading experience. If it holds a little kernel of knowledge that readers choose to explore, well, that's great.

The Internet serves as a channel of endless information through which individuals now access the news, employment opportunities, education, entertainment, etc.

A simple summary of my life is that my parents worked very hard so that I could have a great education, and I took that education and worked very hard to get where I am. I would like my kids' lives to be exactly the same.
