If a long cherished dream comes true for your character, does it work out exactly as that character hoped or do they have to revise their plans to take into account things they had not initially known about? If a long cherished dream turns out to be a disappointment, what does your character do? Do they embark on trying to fulfil a new cherished dream or do they become bitter at the disappointment? If the latter, how does it affect their relationships with the other characters in the story?
Changes of direction can be positive and negative, of course. Usually it's positive for one character, negative for another. But what happens when a change is completely negative - i.e. the character has to flee for their life or go on a quest nobody expects them to survive? Sometimes a document turns up (will usually, sometimes a letter) that can also force changes of direction. What is the fall out from this and is the change of direction a positive one?
