Saturdays are usually pretty busy as I usually play Dungeons and Dragons with friends, do chores around the house and sometimes I also take some time to study a bit so it's very hard to go into lethargy
On Sundays I like to let my heart do what it desires so I have only one rule for this day, which is "no rules" so I just do whatever I want and I try to relax as much as I can before the new week
Your Saturdays sounds like fun, except for the parts where you do chores and study (unless you enjoy studying).
