Just let that sh*t go. We hear it all the time. This simple phrase meant to be a symbolic releasing of our problems. Surrendering our worries into the universe and trusting it will all work out.
I was one of the people that said this so often. It was a motto I thought I lived by, but when I actually thought about what I've "let go" of in my life, it was way more complicated than just a single moment of release.
