I don't often worry about things I can't control because it's a waste of my time and I can't stand wasting time. It's too precious.
But when I have an issue, I break it down point by point and if it's something I can't fix myself or find help with to resolve, then it's safe to say it's something that can't be controlled or changed. I literally grab air, visualize this mass in my hands and open a window and let it out. Once it's out, I see it breaking up into a million tiny particles and watch it drift into space.
Yes, it sounds "off". But so am I. :)
