As we get ready to close out one year and begin another, it feels like a good time to reflect on our lives and reevaluate the things that bring us happiness. Even if you're not a goal setter or resolution writer, it's good to step back and take a look at your life every now and again — especially if you've been feeling time-crunched and stressed out.

One of our favorite sources for inspiration on self-evaluation is the book "Simple Abundance: A Daybook of Comfort and Joy," by Sarah Ban Breathnach. "Simple Abundance" offers 365 essays on gratitude, reflection and self-nurturing (one for every day of the year) that can help you figure out what you need to lead a happier life. (Hint, it's not money, power or "things.")

Here, we've compiled our favorite quotes from the book. Use them as a cheat sheet on your quest to make a life filled with happiness and joy.
