This is similar to the ancient education system in India(Gurukula). The student(shishya) lives with his teacher(guru) for years. I was born in 1987 in a small town in South India. The gurukula system was dead by then but partially alive where i was and so I got to build a 22 year old relationship with my guru who taught me South Indian Classical Music(Carnatic music). Now I am in Boston studying music. I feel like the education system here is way more efficient but ineffective and the opposite back home. The biggest difference i feel is in the quality of experience.
