TV Shows get cancelled all the time mostly because not many are watching which translates to lower revenue and sometimes the leading actor decides to retire or gets the boot.
Use this to talk about knowing when to quit. Do you quit while you're still ahead or try to do everything before giving up? You can also write about why and how quitting isn't necessarily a bad thing and can be quite healthy to purge if they are dragging you down.
How does this affect the new year coming up? Will you be entering it with baggage or will you be purging and quitting things that aren't healthy, worthy of your time or plain holding you back?
