Whether it be sleeping, eating, watching movies/tv, playing video games, or a variety of other things, having free time is very important. Being busy every second and not taking the time to wind down and relax will cause you nothing but stress.
What do you do in your free time? How do you wind down from a busy day at school or work?
I'm a big music fan, and will listen to various songs that just bring down my mood and relax me. There are also some Youtubers I watch who can just make me laugh like crazy.
