Don’t you hate it when you are in a situation so deep that when you realize it’s time to move on and change, that it will now be more painful than ever. But every day you postpone it, the more difficult and painful it becomes. There’s all sorts of examples; a relationship, a job, a house, a friend etc etc.
The best advice is; just do it (Nike) and realize you aren’t making things easier or better by putting off the inevitable.
