We can often feel that to feel happy we need to feel less sad, but sadness isn't the opposite of happiness, boredom is. So if you want to be happier, work on keeping boredom at bay, rather than just trying not to be sad. Build excitement into your life as often as you can, and create laughter and silliness.
Beating boredom means trying new things; saying yes, and leaving your comfort zone. It means not always taking the easy choice of staying in, and vegging in front of the television. It means facing your fears and just giving it a go anyway.
Keep boredom at bay will make you happier. Boredom is the opposite of happiness. Promise ;-)
