I believe gratitude is a miraculous force. So does Zen Habits blogger Leo Babauta, which is why he penned a post about ways to incorporate gratitude into your life. Some samples:
Have a morning gratitude session. Make it a daily ritual to take one minute in the morning to think of the people who have done something nice for you or to think of as many things as you can in your life you're grateful for.
Having a hard day? Create a gratitude list.
Don't get mad; get grateful. Whenever you find yourself ticked off at someone, pause, do a little deep breathing, and try to think of reasons you're grateful for him or her.
Show gratitude to your significant other, rather than criticizing.
Show gratitude for your children, rather than kvetching about them.
Facing a life challenge? Try to see it as an opportunity for learning, growth and improvement. There's always something good to be found within the difficult or tragic.
Concludes Leo: "There's no doubt in my mind the simple act of [regular] gratitude . . . will change anyone's life, positively and immediately."
