It's a funny thing about life, once you begin to take note of the things you are grateful for, you begin to lose sight of the things that you lack.
Life has a tendency to provide a person with what they need in order to grow. Our beliefs, what we value in life, provide the roadmap for the type of life that we experience. A period of personal unhappiness reveals that our values are misplaced and we are on the wrong path. Unless a person changes their values and ideas, they will continue to experience discontentment.
