This is one of my favorite books I've read in awhile, so I'm excited to write a quick review on it.
My mom is a big fan of self-help books and has recommended the only two books I've ever read in this genre;
The Total Money Makeover and
The Happiness Project by Gretchen Rubin. Both of which I'm a big fan of and would recommend to anyone and everyone.

One day, while riding a bus to work Gretchen, the author of
The Happiness Project, was thinking about life. About how she doesn't want to waste life not taking full advantage of what she has or can do, or without truly being happy. But how do you define happiness? How do you know if you're truly happy? Or if you could be happier? Gretchen knew that she had everything that she could ever want at that moment - yet was failing to appreciate it. She wanted to stop taking days for granted so she doesn't come to the end of her life and wish she'd appreciated it more in the moment.
From here, Gretchen decided to dedicate a year to becoming happier. Gretchen being the researcher that she is, researched thousands of books, speeches and real-life examples of happiness, as well as worked through the best way to set up her experiment. In twelve months, she was going to be happier.
The Happiness Project takes you step-by-step through her year of dedicated to happiness. She mapped it out, she tracked it and kept a chart, journaling her way through the year so she can see how she grew. Each month of her year-long experiment was dedicated to different aspects of happiness and becoming a more self aware person.
Her twelve months broke out to the following; Vitality/Energy, Marriage, Work, Parenthood, Leisure, Friendship, Money, Eternity, Books, Mindfulness, Attitude and Happiness.
This is a girl after my own heart. She loves to read and make lists. She's a pessimist who wants to be an optimist. She's a perfectionist. She's basically me, just living in NYC with a family... There were more times I could count where I felt like she was describing myself in detail, instead of recounting her past month during the project.
And her results? It worked! At the end of the book, Gretchen does believe she's happier and feels that the people closest to her are actually happier as well. Now, there's obviously no scientific way to prove that she's actually happier as a result of this year experiment, but if she thinks she's happier and feels happier because of it? That sounds like it worked to me.
I give this book a full five stars. My plan is to read this book again, and take ample notes, make my own lists and give it a shot myself. And I'm pretty excited about it.
