my advice

if you want to stop thinking about a negative circumstance in your life which has many complex pieces of information associated with it, try to mentally reduce all that information to a single piece of information, like a 1 in binary code, so that your mind can switch back and forth between 0 (not thinking about it) and 1 (thinking about it), and gradually you can replace that unpleasant 1 with another 1. the world is full of them

make your life valuable
