The book Candide by Voltaire is about a man that gets into some bad situations but stays optimistic

their journey a storm demolishes the ship. Jacques drowns, and Candide and Pangloss survive only to find an earthquake and tidal wave leveling Lisbon. Pangloss insists that even though the Lisbon has been totally destroyed, “the world is still the best of all possible worlds.” This is him showing his optimism despite their misfortune. Then Pangloss is hung for making such an unorthodox statement while Candide is beaten during a ceremony of the Spanish Inquisition. After this, an old woman reunites Candide with Cunégonde, who survived the Bulgarian raid, the rape, and partial disembowelment she was put through. Cunégonde has now become involved with both Don Issachar and the Grand Inquisitor of Lisbon. After hearing this, Candide murders both of them, then runs away to Cadiz with Cunégonde and the old woman. When he gets there he volunteers to fight the Jesuits in Paraguay. Then they sail to Buenos Aires, however, shortly after they arrive the old woman sees a ship from Spain chasing them.           Candide and his servant Cacambo then go and join the Jesuits instead, where the Commandant of the Jesuits happens to be Cunégonde's brother and the Baron’s son. Everything goes wrong for Candide when the Baron's son forbids him to marry Cunégonde, leading Candide to stab him. Candide and Cacambo getaway but are then captured by the Oreillons, a tribe of Indians, but the tactful Cacambo convinces the Oreillons to let them go. Candide and Cacambo then come across the Utopian empire of Eldorado but leave (with 102 red sheep covered in jewels) to find Cunégonde. Next they go to Surinam where Candide is hustled by a Dutch sailor and a judge. He sends Cacambo to go and get Cunégonde in Buenos Aires and to meet up with him afterwards in Venice; where Candide befriends Martin, a very pessimistic person. Candide and Martin then sail to Bordeaux. While in Paris, Candide becomes sick and loses money to various swindlers. Then they sail to England where they observe the public execution of an English admiral who did not kill enough people. They finally make it to Venice and meet Cacambo, and then all of them sail to Constantinople. On the journey, Candide, Martin and Cacambo find Dr. Pangloss, who survived the hanging, also Cunégonde's brother, the Baron's son. They all then come across Cunégonde and the old woman and the Baron's son forbids Candide to marry his sister once more, so Candide sends him back to the galley ship. Candide eventually settles down on a farm with Cunégonde, the old woman, Martin, Cacambo, and Pangloss. After much theoretical debating between Candide, Martin and Pangloss, Candide announces that one must stop philosophizing and cultivate one's garden as the only defense against boredom and dissatisfaction.        Candide went through a lot of bad times and hardships but he stayed optimistic the whole time. I think this book teaches a very good lesson which is “If you stay optimistic, you can accomplish anything.” Because what he really wanted in life was to be with lady Cunégonde, and even though he was forbidden and it looked like he would never see her again many times, he kept his hopes up and in the end, he got her.
