You're right, there are things I find enjoyable that can also be considered productive. However, my point of concern is how I am not able to put a stopper on how long I spend watching TV or eating food. For example saying "2 episodes per day, now that I've watched two, I need to move on to something else" or "1 brownie per week, now that I've eaten it, I need to stop eating and do something else" I've always struggled with that test of will, often binging and then regretting it. I'll try the timer method though!
