The 5th Wave is a book about aliens invading earth. In this book, the humans have to use many of the Seven Habits to survive.
The main habit that I want to focus on from the story is Be Proactive. Be Proactive is the first habit. In one scene, a sniper is shooting a 50. caliber round at one of the good guys named Cassie. Cassie has to find cover, which in her case is under a Buick. When Cassie was running for the Buick she got shot by the sniper. She uses a belt to survive by tying it around her leg to slow the blood loss.
While Cassie is under the car she also has a handgun near her. She keeps an M16 by her side. She waits under the car until she has the cover of darkness to escape. She does this so she will not be followed.
This is just a part of the story of how the book The 5th Wave and the characters in the story use the Seven Habits.
