How to stop watching TV shows/moviesIf you want to stop, you stop.
I know it is easier said than done. So here is what you can do:
Write a small note on your homescreen about how watching so many movies causes trouble in your life. Read this everytime you feel the urge to watch a movie.
And if at any time you find it too difficult to resist, impulsively switch off your computer/laptop and go for a walk. Let me assure you that during the walk you will appreciate yourself for making that impulsive decision.
Use all this a few times and you'll be good!
Someone recently told me their trick - set the rule that you'll only watch TV while working out (like on the treadmill at the gym). Good motivation to work out and sets a strict limit to follow.
Personally, I just naturally fell out of the habit of watching TV once I moved to a new place and my roommates didn't have cable. Lived without it for about a year and now I just don't even know when most shows are running, and eve now that I have cable again I only make time for a select few shows, which I watch on weekends with my boyfriend (through On Demand or Netflix).
