I have been working on a Do Not Complain project on and off since April 2008. That's over ten years now! The idea behind this is to find gratitude in each day. If you run into a challenge, like a waitress brings you the wrong dish, you can calmly and rationally ask for that problem to be fixed. It's ok to speak out when there is something not right. The key is to do it in a healthy way. There is no need for yelling or whining or hostility. The more we all bring peace and maturity to our world, the more we all benefit.
Will you join me in this project? Take it one day at a time. Each new day, focus on being grateful for what you have and compassionate toward those around you. See where you had challenges. Learn from them.
