Nutritional things are objectively valuable in themselves. Good is objectively good in itself. A superior is objectively superior in itself. All these things carry the essence of being self-sufficient – not needing external validation or rather external opinion can never change their nature. In the same line of thought, " I AM WHO I AM" translates to – God he is not dependent on human mind for existence. "ALL" is dependent on God's word for existence. Being shy or fearful indicates you're not self-sufficient.
