There are thousands of agreements you have made with yourself, with other people, with your dream of life, with God, with society, with your parents, with your spouse, with your children. But the most important agreements are the ones you made with yourself. In these agreements you tell yourself who you are, what you feel, what you believe, and how to behave. The result is what you call your personality. In these agreements you say, "This is what I am. This is what I believe. I can do certain things, and some things I cannot do. This is reality, that is fantasy; this is possible, that is impossible."
One single agreement is not such a problem, but we have many agreements that make us suffer, that make us fail in life. If you want to live a life of joy and fulfillment, you have to find the courage to break those agreements that are fear-based and claim your personal power. The agreements that come from fear require us to expend a lot of energy, but the agreements that come from love help us to conserve energy and even gain energy.
