Here’s another piece of wisdom that’s become one of my personal mantras, from Dr. Lissa Rankin.
You resist change, and yet change is inevitable. How do you expect to be happy when you’re always resisting what is? Why can’t you just be with what is? Accept what is happening right now. Accept what happened in the past. Accept that you can’t predict or control the future. Accept this moment and pay no attention to any other moment other than RIGHT NOW. In this moment, you will find peace.
