Because one believes in oneself, one doesn't try to convince. Because one is content with oneself, one doesn't need others' approval. Because one accepts oneself, the whole world accepts him or her.
Go on bravely. Do not expect success in a day or a year. Always hold on to the highest. Be steady. Avoid jealousy and selfishness. Be obedient and eternally faithful to the cause of truth, humanity, and your country, and you will move the world.
