This problem will probably fix itself once I have children, but until then... I'm curious, if you enjoy your weekends, what does your weekend schedule look like?
Rest takes priority, always. It should be properly relaxing. A common trap is social media, gaming, or some other activity that is not exactly rest. Non-rest idleness is how the weekend goes by unproductively.
Next, maintenance. Laundry, groceries, mopping, wiping, cutting grass, cutting hair, visiting relatives. Yes, you have to maintain relationships too.
And then energy stuff when there's excess capacity. Sometimes we drive to a random town, buy groceries from the beach. Throw a party. Build a side app. Hiking. Going for a run.
Reenergizing isn't always just lying down, sometimes you need to move actively too.
Otherwise, weekends are to be enjoyed outside.
(During the week though, 2 hours every morning before work, working on the business, no excuses)
I wake up without an alarm, take a quick shower, open my notebook and write down the tasks I would like to accomplish for the day.
I then get to work.
I will take longer lunch and diners with friends.
I drink beer, hang out with my wife or do sports
Or vice versa.
Routine is better for me.
Good luck.
