I know it's a meme but I don't understand why people don't just use night motivation at night. Nowadays there is only a very limited amount of activities that can't be done at night.
When you are on your own schedule, yes. Otherwise you have to deal with the schedules of businesses and people who aren’t available at night. My doctor won’t see me at midnight, after all.
You could still mop the place. Or at the very least sweep it. Or do all other cleaning tasks that don't involve the vacuum.
As I said elsewhere, I get it if you have no motivation. If you don't feel like doing something, it's hard to get started. But if are motivated it's better to do something than nothing.
