A few years ago a person who would be considered successful by most people's standards shared with me, "Looking back at my childhood, a pattern that I remembered having is, ‘He has more than me.' ‘His birthday present was better than mine.' ‘He gets to travel to more interesting places.' ‘He is luckier than I am.' ‘He has more friends.' ‘He lives in a nicer house.'
"On my fortieth birthday I made a mental accounting of my life. I thought about various traits and patterns that I had. The most distressful part of this mental accounting was that I noticed I wasn't very happy in my life. When I asked myself why, and thought about it, I realized that I kept feeling that I had less than others. I was told to look back at my childhood for this pattern, and that's when I realized how often this theme came up. There were many ways that others had it better than I did. And my mind was full of thoughts of not only having less, but of being less.
"I realized that if I wanted to live the rest of my life joyfully, I needed to do one of two things. Either I could make it my goal to be so successful in every way that is important to me that I would be far ahead of everyone I knew. Then I would find it easier to be grateful for my accomplishments, successes, and possessions. Or I could learn to gain greater mastery over my thoughts. I would choose to think thoughts of gratitude as my automatic way of thinking. The first choice would take so much time, effort, and energy that I would be in a constant frustrating race with others. I might never reach my goal and even if I did reach it, it was certainly not going to last. Eventually someone would pass me by. This way of thinking would give me many years of stress and frustration and there really wasn't a way that this would give me gratitude and happiness. It was obvious that the wiser approach would be to be grateful for what I had. Choosing this pattern of thought was one of the best choices I have made in my life."
