The cure for bitterness and resentment is a courageous act.
Let’s take for example a difficult conversation.
The mere thought of it will terrify most and they will dismiss their bones of contention as minor manageable inconveniences.
On the other hand, if one goes through with the tough conversation then the bitterness and resentment are replaced with a feeling of peaceful satisfaction for having done something brave about it.
