Do Hard Things. The authors, Alex and Brett Harris, list five kinds of hard things. The first two are things that are outside of your comfort zone, and things that go beyond what is expected or required of you. These two ideas are a challenge to our young culture. Brett and Alex use many examples to explain these two ideas. They say that if people, not just young people, want to better themselves, then they always push themselves to do more. I agree with this statement, we need to strive to do our best and go beyond what is expected of us. There is so much that people can do if only they would go out and do it.
