I've been able to look at the world differently from three continents practically. I've always lived between India and the U.S. When I married Mahmood I became a daughter-in-law of Africa. That really changed my worldview. I can see it from so many perspectives.

The dignity of everyday life - the beauty of it, the attitude of it - is what I live around. And it is never on screen, and it is certainly never associated with Africa. If we see Africa at all, it is always used as a backdrop: a big blob of a continent rather than a specific street or a country or a place.

Startups need to focus on building a foundation for their company culture early, and then they need to revisit it often. Every time a hire is made, a feature is launched, a Facebook status is updated, a press interview is given, a round of financing is raised, or a meeting is held, culture should be part of the decision-making process.
