The Four Agreements is a book written by Don Miguel Ruiz that offers a practical guide to personal freedom. The book is based on ancient Toltec wisdom and offers four principles to practice in order to create love and happiness in your life.

Here are the four agreements to become your best self:

Agreement Number One: Be Impeccable with Words.

The first agreement is to be impeccable with your words. Your words have the power to create the most beautiful dream or destroy everything around you. Speak with integrity and say only what you mean. Avoid using words to speak against yourself or others.

Agreement Number Two: Don’t Take Anything Personally.

The second agreement is to not take anything personally. Nothing other people do is because of you. What others say and do is a projection of their own reality. When you are immune to the opinions and actions of others, you won't be the victim of needless suffering.

Agreement Number Three: Don’t Make Assumptions.

The third agreement is to not make assumptions. Find the courage to ask questions and to express what you really want. Communicate with others as clearly as you can to avoid misunderstandings, sadness, and drama.

Agreement Number Four: Always Do Your Best.

The fourth agreement is to always do your best. Your best is going to change from moment to moment; it will be different when you are healthy as opposed to sick. Under any circumstance, simply do your best, and you will avoid self-judgment, self-abuse, and regret.

By following these four agreements, you can become your best self and achieve personal freedom. Remember, these agreements take practice and dedication, but the rewards are worth it in the end.
