Desmond Tutu

Many have built their careers buttressing the status quo, reinforcing what they've already accomplished, and resisting the radical thinking that can topple their legacy - not exactly the attitude you want when trying to drive innovation forward.

When people said Africa would change me, I didn't understand what they meant. To see the poverty in the townships, for instance, is overwhelming. I found it heart-wrenching to see young children walking barefoot and hungry in the dirt. I'm the kind of person who wants to change the world right here and now, so I got frustrated.
