Appreciation aches
There's not one thing that has ever been taken for granted by everyone at the same time. Oxygen? There's someone appreciating the air right at this moment. Nitrogen? Someone has just learned about it at school. Nails? Blood? Pupils? Everything is being appreciated at this moment in time by someone somewhere.
You?
You can argue that you have never been appreciated at any moment. I beg to differ. Someone might've looked at you at the streets and had a sudden realization that changed their lives for the better; a little kid might've looked at you and right away wanted to be like you when they grow up; You might've been in a rush and bumped on someone on their way to work and because of that they weren't hit by a bike that was passing by a few moments later. There's always something to appreciate at life and there's always something being appreciated.
We live in a planet that's inside a solar system that's inside a universe full of everything. And sometimes, that's exactly how we feel. Full of everything. When that feeling kicks in and everything seems a little hopeless, remind yourself that the world is full of everything as well. A little bit of appreciation might help.
