Backwards plays contextual audio, based on your working behaviour.
The continual feedback will gradually teach your brain to work on your side rather than against you. Over time, you'll naturally form positive habits.
If you are reading technical documentation, you'll hear positive audio designed to hold your focus. If you start watching videos on YouTube, you'll hear unpleasant audio designed to steer you away.
I have considered strategies and features which go far further than using auditory feedback, but those ideas are for future versions. I feel that a solid MVP is possible based on the ideas above.
