Patience serves as a protection against wrongs as clothes do against cold. For if you put on more clothes as the cold increases, it will have no power to hurt you. So in like manner you must grow in patience when you meet with great wrongs, and they will then be powerless to vex your mind.
Leonardo da VinciWherever good fortune enters, envy lays siege to the place and attacks it; and when it departs, sorrow and repentance remain behind.
