A roster system can work if youve got a lot of people sharing the house.
depends on how many people. Otherwise designate the tasks that you want to do and do best. Rich people dont need to do this, they employ housekeepers and staff.
Ive always wondered what the other half do when they have staff to do evrything and they have a lot of free time. Apparently the uber idle rich, or aristocrats really had nothing to do when everything was done for them, so they travelled instead and did volunteer work, like help in soup kitchens, do charity work etc.
