Well. You can't stew. You have to let shit go. And, really, stirring the shit, is no way to spend your precious time. So you spend lots of time letting things go, clearing your space, so you can fill it with other shit, which you then let go.
It's a process. Sounds sort of shitty, but it's essential. Take in the world, and let it go. Don't take anything personally, even though everything seems personal. In and out. It's a flow thing. Go with the flow and let it go.
