Here's a theory and I'm pretty sure it's true but I'm still dwelling on it..
No matter what's happening, don't worry about it, because you're helping somebody, somewhere.. and evolution and time always move forward.

..it's like Bobby McFerrin's Don't Worry, Be Happy except with the explanation.
okay, it's not like that because i never sang like bobby mcferrin, and i didn't write the song.. but still, you know.
