I will stop tickling the cat when she is not looking.
I will at least attempt to go on a diet – for a few days, anyway.
I promise to get rid of all the clutter in the house, even if every little piece of junk has a memory associated with it (“I played a lot of 45’s on that beat up old record player, which just needs a little pounding on the side to get it working again!”) or might be useful someday (“You never know when you might have a sudden need for leftover waxed paper!”)
I will never again get mad and yell at anyone, except for assholes who deserve it.
Even if I am a New Yorker, I will not speed up at yellow lights, to try to make it through before they change to red.
I will stop spending money on things I don’t need, except for things I really want, to the point where it would be damaging to my mental health if I don’t buy them. This could be practically anything.
