In a world of growing food demand, Africa is home to two-thirds of the world's unexploited arable land.

If you are African, the more educated you are, the less chances you have of getting a job.

Nobody messes with China, nobody messes with the United States, or with Europe, because these are really big entities with a lot of clout and a lot of economic power. They have a place at the table.

You fly for hours and hours and hours over Africa to go from one place to another.

You have got to attract the brightest and the best, but the brightest and best won't stay unless they see real career options.

It is unrealistic to expect an entire profession to be completely good. There are bound to be some individuals who are stressed, who are unkind, who are a bit rubbish at their job, who are in the wrong career.

I am blessed to have worked in big-budget films at an early stage of my career.

I used to work at NASA in Virginia. It was nothing glamorous; I was just tasked with making code compile for obscure projects, and I wasn't very good at it. Now I spend most of my time drawing pictures and looking at funny things on the Internet, which in retrospect is largely what I did at my old job, too.
