For many people happiness comes only in fleeting moments, such as landing that dream job, or meeting that perfect guy or girl, but few feel truly happy most of the time.

Of course, we all go through life's inevitable ups and downs, but there are ways to boost your happiness level in order to feel joyful more often.

The quality of your relationships, whether platonic or romantic, play a major factor in how happy or unhappy you are. In fact, studies have show that those who enjoy high quality relationships tend to have a lifespan that's twice as long as those who don't.
