“Happiness and freedom begin with a clear understanding of one principle. Some things are within your control. And some things are not.” By Epictetus
This is a perfect mantra for letting go and letting be. The past is the easiest one to apply this concept to. We cannot in any way change the past. What’s done, is done. We can only act now on the situation. We can act with intention, but the outcome will still be out of our hands. Please never use this to give up. Intention is very powerful and is action. Moreover, please use this as a reminder of the futility of worry. Worry is inaction. Take the action that follows your best intentions and rumba your best intensions are always based on what you know up to know. Let the future determine the infinite possible outcomes. When they occur, act with the new results in mind. Always move forward, starting now. You can only do what you can do. If you could do any differently, you would.
