Life is generally thought of in terms of gain, not loss. Gaining a diploma, a job, a spouse, children, a house, a car or two, and toys is fun and fulfilling. Loss is a negative conception; unhappiness blooms and grows from loss of a job, money, spouse, etc. Without loss however, there is no gain. Lose money and realize it’s better than loss of health. Lose a spouse and know that love can arrive by many roads and be stronger than the first love. Lose a house, a job, a car, and realize that happiness can grow under many roofs, and jobs are there for anyone willing to walk or ride a bike to them. Lose a friend or two, and come to know yourself as your best friend. Lose your heart and faith, and gain a void where new faith, and a new heart can grow.
A teen I once knew well, idealistically pure and clear, saw this before I did. When I was sixteen I knew that a person could lose everything, and still live. Lose a stomach, gain mobility, and see those feet which took you on journeys before now, and can take you on adventures still.
