Ownership vs sessions - what makes you stay obedient long-term?

Question for both sides.
I've been running long-term ownership dynamics (daily tasks, check-ins, psychological control) vs short physical sessions and I see way higher retention with ownership.
For subs: what keeps you obedient after the first week? Mental ownership or physical?
For Doms: how do you keep the dynamic alive without burning out?
Looking for real experiences, not just fantasies.
