How do I know if a major life change is actually changing who I am?

Sor Juana spent her whole life asking: when does a transition become a transformation of self? Here's what she understood that matters: a real identity shift isn't just about circumstance changing around you. It's about what you *choose* to do with new knowledge, new constraints, new freedoms. When you move cities, change jobs, end a relationship, or step into a new role—you're not automatically a different person. But you are in a position to become one. The question isn't whether the transition changed you. It's whether you're using it as a moment to think differently about who you want to be. Sor Juana wrote her way through her own transitions: convent walls, intellectual isolation, censorship. Each one forced her to ask harder questions about her own mind and her own rights. That's the work. You'll know it's a real identity shift when you can't unknow what you've learned about yourself, when you stop fitting neatly into your old patterns, when you start asking different questions about what you deserve and what you're capable of. Pay attention to what you're reading, who you're becoming in conversation, what you're suddenly angry or grieving about. Those are the signals. The transition is just the opening. You do the rest.
