“Darkness has a hunger that’s insatiable, and lightness has a call that’s hard to hear.” It’s true that our brains are more prone to focus on the negative than the positive. It makes sense.

So, if working on happiness is seven times harder than giving into the darkness, is it worth it? Anyone who smiles more than they frown would say, absolutely. And why not have fun trying!?
