You will become as small as your controlling desire; as great as your dominant aspiration.
Consider this quote from James Allen, author and an early writer in the self-improvement arena. What is your controlling the desire, the foundation of the the majority of your choices and actions? What is your dominant aspiration--to be a great composer, to climb Mt. Everest, to travel, etc. ? Are your desire and aspiration harmonious or do they conflict?
Answer these questions. If you find that they are in conflict, try to determine how you may bring them into accord.
