Why are you Happy?

I am just starting a new book. Its called The Happiness Project by Gretchen Rubin. She explores different things or ideas that make a person happy. Everyone is obviously different and would have different ideas..So she picks 12. Some she's never put to the test and others she knows have generally made her happy before. For example, singing in the morning, Cleaning her closets, reading Aristotle or generally having more fun. Each month she full heartily engages her self/life in the "task" and describes if, why and how it changed her overall happiness and what else she learned.
My educated, book worm friend gave this to me and said that it is in her "I LOVE IT!" category.
For the most part, I would say that I have a LOVE for life and trying to live each day to its fullest. Heck, I'm a psych major so, the things that make people unique and tick have always interested me.

In addition and side note: this time of my life; meaning my family that I grew up in, my parents and siblings, is ROUGH. To say the least. The regular roller coaster ride has been a bit more out of control, with new twists, no seat belts, and an end far off in the distance. I am still happy, because humbly and thankfully SO many of my other "life rides" are ever so smooth and more exciting than I could've imagined.
I've just pondered more lately, like the author Gretchen, what makes one happy and why? I suppose some things are always changing...But the REAL reasons for happiness, I believe, are the constants.

I guess I've just felt a constant reminder and spirit that I know the gospel of Jesus Christ and living worthily by his commandments are the surest way to achieve True Happiness. With this we can hold tight and make it to the end of all our life roller coasters. Even if we are pregnant and throw up a few times along the way.
