Fyodor Dostoevsky

“Above all, don't lie to yourself. The man who lies to himself and listens to his own lie comes to a point that he cannot distinguish the truth within him, or around him, and so loses all respect for himself and for others. And having no respect he ceases to love.”
― Fyodor Dostoevsky, The Brothers Karamazov

“Pain and suffering are always inevitable for a large intelligence and a deep heart. The really great men must, I think, have great sadness on earth.”
― Fyodor Dostoevsky, Crime and Punishment

“To go wrong in one's own way is better than to go right in someone else's.”
― Fyodor Dostoevsky, Crime and Punishment

“What is hell? I maintain that it is the suffering of being unable to love.”
― Fyodor Dostoevsky, The Brothers Karamazov
