Call to Adventure
The call to adventure is the event in the hero's story that gives them the opportunity to take action and start the journey. There are different reasons for the call. One could be a quest to reclaim something that has been taken from the hero. A second, is that the character is missing something in their life and they go out to find it. A third, is that the character wants to restore honor. A final reason, is that they want to gain rights for their people, so they fight for those rights.
Shrek's reason, is the first example. Lord Farquaad exiles all of the fairy tail creatures and they all go to Shrek's swamp. They take over his swamp and he wants to get it back for himself.
