Read, listen, watch, feel, do, surround yourself with things that makes your heart happy. I don't know why such a simple concept can be lost to us to easily, so readily. Happiness scares us more than anything in the world. It's not just the fact that is can be taken away as quickly as it came and a million times harder to get back. It's because we're afraid of where it comes from, whether we deserve it. It's such a huge emotion that we don't know how to handle. So sometimes, we jump at the sight of anger, tension, unhappiness just so that we don't have that responsibility, the responsibility to keep it going, to take care of it. Because if we stuff up, then the feeling that it was your own fault that you lost that happiness kills you.
The thing about happiness is that it makes us feel like we're invincible, on top of the world and free. But even when we lost it, we have to remember that no one's invincible, just cataclysmically human; we're not on top of the world all them time, but the world keeps spinning no matter what; freedom however is always there, alongside happiness. We just have to find ways to reach it and surround ourselves with it.
