Warning: second Lord of the Rings clip. But I have to show these two. The first one is where Frodo essentially loses faith because things have gone from bad to worse and there seems no way out. But he has his friend, Sam, there to remind him why one has to keep fighting.
The same happens to another hobbit, Pippin, and Gandalf has to set him straight.
Have you ever been tempted to give up? Journal about the experience.
