Lol - I came up with basically the same system to use on myself, having realized I’d become too much of a couch potato. I have a piggy bank full of quarters, so I just use those instead of tokens. If I want to watch TV an/or have a cocktail, I gotta earn the quarters to cover that by doing chores or errands, exercising, practicing music, processing email, etc. I still watch maybe too much TV, but now at least I’m getting stuff done that had been hard to get around to in the past.
