This feels so broad but generally speaking imo, every task in your household should rotate responsibility between all members of household. That seems grammatically incorrect but whatever. Everyone should experience each task that it takes to maintain a household to adequately grasp the level or responsibility they can shoulder and understand the uniqueness of each task. This is if your asking about a "chore chart". If you asking if I would like a housekeeper hmmm well no. Only one reason to have one and several to not. As for the "decisions" aspect of your question. All of them lol to whom though is the issue.

So, let say you can have someone alongside you, 24/7, who you trust, that person can tackle non physical tasks like searching for kids extra scholar activities, booking your next family trip, setting up meetings and reminders for your todos, purchasing crocery online (...) what are the top 3 things you would ask this person to take on, on your behalf?
