Communists must be ready at all times to stand up for the truth, because truth is in the interests of the people; Communists must be ready at all times to correct their mistakes, because mistakes are against the interests of the people.
Mao ZedongAt no time and in no circumstances should a Communist place his personal interests first; he should subordinate them to the interests of the nation and of the masses. Hence, selfishness, slacking, corruption, seeking the limelight, and so on, are most contemptible, while selflessness, working with all one's energy, whole-hearted devotion to public duty, and quiet hard work will command respect.
Mao ZedongWe must thoroughly clear away all ideas among our cadres of winning easy victories through good luck, without hard and bitter struggle, without sweat and blood.
Mao Zedong
