What was Hestia the goddesses education?

Hestia, being one of the primordial Olympian deities, didn't receive an "education" in the human sense. She was born, essentially, fully formed and with her divine powers and attributes. Her knowledge and understanding of the cosmos and her role within it were inherent to her being, not learned. There's no mythological account of her attending a school or receiving tutelage from another god.
