It always seems impossible until its done.
–Nelson Mandela
When Seth and I were in Africa, we were fortunate enough to visit 2 of the 3 prisons where Nelson Mandela was detained, the most striking and memorable to us was Robben Island, where he was held for 18 years, for fighting for the freedom of people. Still today, after everything he has encountered and all the persecution, he remains positive and optimistic.
I bet this part of your trip was REALLY fascinating.
