Remember, dear reader, that you were in nothingness for millions of years, and our fate is all death and a return to nothingness for millions more until God wishes to revive us again. Nothing remains but the good legacy and the deeds that changed the course of history. Therefore, I have collected the sayings of one hundred personalities from around the world, including natural personalities and some without legal authority. Looking at their religions, sects, and intellectual and political orientations, they were not united by skin color, race, gender, or social class. They were united by the wisdom that they wrote down and left to us after them.
