To help you find peace at night regardless of how your actual day was thank the things that went well. An example is you can thank your car for getting you to work. Thank the alarm clock that got you up this morning. Thank the stop lights that kept you safe at intersections. This practice will help you to be grateful for the smallest things in life. It will help you to see the true wonders of the small things that you neglect each day. You will go to bed on a positive which will help you stay calm and relaxed.
