Crystallized self is a way of thinking about ourselves. It's something that takes time and effort to form. It is the identity that we form over time with all of the things that have happened to us and the choices we have made in our lives. Crystallized self is the beliefs, values, and life experiences that make us who we are. When we think of ourselves in terms of our crystallized self, it can help us make decisions, understand our behavior, and work toward goals we set for ourselves.
