People need to have a heart that sacrifices their own self-interest. -(Russian writer) Turgenev
A person's sacrifice is not for others, but for himself. If you don't feel happy when you die, go to hell! You don't deserve life. Romain rolland (French writer)
Take the happiness of others as your own happiness, give flowers to others and keep thorns for yourself! Valdes
If a person's whole personality and life are devoted to a moral pursuit, if he has such power, and everyone else is small compared with this person in this respect, then we will see lofty goodness in this person. -"On Sublime and Funny"
