"Gratitude makes relationships flourish. As you increase your gratitude for any relationship, you will magically receive an abundance of happiness and good things in that relationship. And gratitude for your relationships doesn't change only your relationships; it also changes you. No matter what your temperment is now, gratitude will give you more patience, understanding, compassion, and kindness, to the point where you won't even recognize yourself. The little irritations you once felt and the complaints you had in your relationships will disappear, because when you're truly grateful for another person, there's nothing you want to change about that person...Words are very powerful, so when you complain about any person you actually harm your life. It is your life that will suffer. By the law of attraction whatever you think or say about another person, you bring to you. This is the very reason why the greatest minds and teachers of the world have told us to be grateful." The Magic by Rhonda Bryne
Here is a fascinating statistic on relationships in Rhonda Bryne's book
The Magic, "...for every one complaint about another person, whether in thought or word, there have to be ten blessings for the relationship to flourish. Any less than ten blessings and the relationship will deteriorate..."
This is a good reminder--based on research--to not take people for granted, but to remember appreciation and gratitude.
