Today is the first day off I've had in a while, where I haven't had any obligations getting in the way of what I want to do for a change. I watched a dvd I borrowed from a buddy some time ago. I actually feel rested despite staying up until about 4am for no reason last night.
Those are rare for me since I work full time, take a full class load, and do part time freelance work BUT when they do come around I lay in bed all day. I'll turn on Netflix and go back and forth between reading and playing video games. Since I stick to a very healthy diet and workout routine, on those days where I can just be lazy, I tend to not do much exercise and I let that day be my cheat day and I eat whatever I want. I'll almost always take a nap on those days because the older you get the more rare naps become.
I actually just have days off, since I'm too sick at the moment to work or to go to school. So I just play animal crossing, draw a lot, and visit friends.
It depends on what needs to be done. I like to finish chores whenever I get the chance and afterwards I wind down on the couch to play a video game or scroll through my phone
