I absolutely agree with what you think of being grateful in life. We are given quite abundant goodness from the universe. When we feel grateful, we will attract more of the goodness, and that will make our lives more wonderful. The universe itself has its own way to provide us with what we may need.
I experienced some little happenings in life which strengthened my belief in the power of Law of Attraction. I chose to be grateful for what happened to me, instead of feeling bad about it. That way I can face life more positively.
