This is your reminder to keep a hobby of some sort. Do something you enjoy. Something to let your creativity out. Don't let the system drain the humanity out of you.
I play drums, but I was blessed enough to save up while living at my parents house to be able to buy my drumset. I don't have that option now. It doesn't need to be expensive. It can be drawing, or if you live somewhere where you can set up a cheap forge and buy a cheap hammer and start making railroad spike knives. I don't want to keep rambling on, I think I made my point. They want us to be good little worker drones. Don't give in to that.
