Always Do Your Best
The fourth agreement is to always do your best. Ruiz explains that this agreement allows the other three to become deeply ingrained habits. He emphasizes that 'your best' will vary from moment to moment, depending on circumstances. 'If you do your best, you will feel good about yourself even if you still make assumptions, still take things personally, and still are not impeccable with your word,' Ruiz writes. This agreement encourages continuous self-improvement and self-acceptance.
