Only you and you and alone can determine how fulfilling your life is and has been. Be honest and true to yourself, and do not compare your life to the lives of others.
There are many paths through the Ring of Life. They are a constant movement toward self-fulfillment through growth of your mind, expansion of your experiences, widening of your senses and growing your spirit. It's ceaseless and constant throughout one's life.
Self fulfillment thinks of how something serves me. Self development thinks of how something helps me to serve others. With self fulfillment, feeling good is the product. With self development, feeling good is the by-product.
John C. Maxwell
Success, I would find out, is interior. It has to do with self-fulfillment and the joy of living.
