When you feel discouraged or simply lazy, as is bound to happen sometimes, remember the millions of people in the world who have not had your privilege. Remember the poor and obscure lives of those countless millions who suffer from every sort of deprivation and frequently find themselves the unwilling victim of wars, and a variety of cruelties, perpetuated by man on man. Is it not significant that the first bid for self realization, among the poor and downtrodden, is to assert their right to education?
