I do many things to spend my free time.
Firstly, I am an avid reader. In my free time hence, I try to read as many books as I can to pass the time.
Next, I listen to music. I have different playlists made on Spotify for this very purpose to suit my various moods and tastes!
I also watch shows to pass my time. I currently am, in fact, watching the BBC Sherlock series at the moment and am tremendously enjoying myself!
If none of these work, I resort to, well, my last resort– sleep!
