There is a really good article in the February Ensign called “What Can The Book of Mormon Teach Us About Happiness”
It lists and talks about 7 principles of happiness that are found in just 2 Chapters of the Book of Mormon!
- Maintaining uplifting associations
- Aligning actions with beliefs
- Accomplishing hard work
- Focusing on the Temple
- Sharing what we have
- Belonging to a family
It is written by Hank R Smith an Instructor at BYU.
You should go read it yourself, it is worth the time.
