True justice is paying only once for each mistake. True injustice is paying more than once for each mistake.
The first agreement
Be impeccable with your word.
Self-rejection is the biggest sin.
You can live in heaven in the middle of thousands of people living in hell because you are immune to that hell.
The second agreement
Don’t take anything personally.
If you don’t take the emotional poison, it becomes even worse in the sender, but not in you.
