The mind thinks of the self as separate, the heart knows better. As one great Indian master, Sri Nisargatta, put it, "The mind creates the abyss, and the heart crosses it."
Unless we are creators, we are not fully alive... Remember, the root word of humble and human is the same: humus: earth. We are dust. We are created; it is God who made us and not we ourselves. But we were made to be co-creators with our maker.
