And I’ll say it again, since you asked me nicely. 
A Tree Grows in Brooklyn by Betty Smith is the book that changed my life. It’s about a girl named Francie growing up in turn-of-the-century Brooklyn in poverty. It’s about how her family came together and what goes on as she grows up.
It is the most hopeful book I have ever read. It is never base or filthy, but it is painfully honest. Smith is completely truthful about being a poor child in the city. I can relate to that, and this book truly made me believe that I could be and do anything, that I could overcome all of my past hardships and be somebody worth being. It taught me to cherish the past, whatever pain it may have brought me, and to look forward to the future with the purest hope inside of me. Someone said that Wally Lamb, another excellent author, loves his characters more than God does. The same is true of ATGIB - with every page, every difficulty, every heartbreak, Smith and I are there with Francie, Neeley, Katie and Johnny, loving them like family, wishing with all we have that they will make it, and feeling true sorrow if they don’t. And although Smith is completely honest in what she portrays - every character is inherently flawed and gifted - you see her love for each person with every word she writes.
This is the book that truly taught me about the sort of person I want to be and showed me that the world is a gift open before me. I can honestly say, looking back, that most of my current happiness, peace of mind, and joy for living stems from this book.
What more can I say? It is a piece of someone’s life, written out in true, honest, beautiful language for you. Imagine how much you have grown in 17 years; reading this book is like living an extra 17 years, learning lessons that you may have missed the first time, understanding the motivations and sadnesses and loves that drive you. You can spend 400 pages in another person’s life, and it will make you appreciate what you have in ways you can not imagine. It will cause you to see, in stark black and white, the greatest possibilities that are before you; at the same time, it will foster a love in you for all the beautiful shades of gray.
I truly believe the world would be a better place if everyone read this book.
