The Four Agreements

Be impeccable with your word: Speak with integrity. Say only what you mean. Avoid using the word to condemn or hurt. Words have power, so use them carefully to create positive change.

Don’t take anything personally: Other people’s actions and words are a projection of their reality onto you. Let go of others’ opinions and free yourself from unnecessary suffering.
Do Not Assume: Assuming about others’ thoughts and motives or actions is typically wrong and leads to malice and conflict. Rather, communicate openly to eradicate misunderstanding and find clarity
Always Do Your Best; This means putting your absolute effort into everything you undertake but accepting that “your best” will vary based on the circumstances. This goes to foster self-acceptance and prevents regret.
