I don't even think much about politicians. I think about the people in the audience who applaud the politicians. They are your fellow countrymen and they're the ones you live with - that should be who we target for education and enlightenment.

When you visit countries that don't nurture these kinds of ambitions, you can feel th absence of hope...people are reduced to worrying only about that day's shelter or the next day's meal.

Some memories are best absorbed through your eyes in real time, even if you have no record of it later. Because then you can access that memory and how you felt in that moment.
