This is one of the absolute hardest things for me to do. I was grateful to find the book, "The Four Agreements" by Don Miguel Ruiz, it opens up the opportunity to remind me why it's important to not take things personal! I've read it probably half a dozen times and every time it sticks for a few months then I slide back into Ego.
The humanistic side of us makes it difficult to deal in a world where so much is thrown at us daily. It's just another reminder to give things to God and let them go! But yet another thing that's hard to do!
