This book lives up to it's title. It inspires you to "Do Hard Things". This book encourages young people to go beyond what is expected of teenagers today, to "rebel against low expectations".
The fact itself that when this book was written, the authors were teens is a testament to the book itself.
I liked that the way the Harris brothers proved their point, and encouraged, was through different types of stories. For example, in some areas they would quote Bible verses and connect how they tie in to every day life. In other places they would give modern day examples of teens who were inspired, and did hard things and give personal stories and anecdotes.
One of my favorite messages in the book is that hard things can look different for everyone. For some people, it can be starting a blog or a mission group to build wells overseas. For other people it can be playing the piano in public, or making an effort to get along with a sibling. It doesn't matter how big or small it is. What matters is that you do the hard thing.
I would definitely recommend this book to all pre-teens and teenagers. Although geared specifically towards adolescents, it would also probably be a good read for adults.
I rate this book 5 out of 5 stars.
