In the long run, your human capital is your main base of competition. Your leading indicator of where you're going to be 20 years from now is how well you're doing in your education system.

I have been struck again and again by how important measurement is to improving the human condition.

Almost half of the population of the world lives in rural regions and mostly in a state of poverty. Such inequalities in human development have been one of the primary reasons for unrest and, in some parts of the world, even violence.

To follow the path that others have laid before you is a reasonable course of action; therefore all progress is made by unreasonable men.

The human being is in the most literal sense a political animal, not merely a gregarious animal, but an animal which can individuate itself only in the midst of society.

All progression is in the relative world.
