Don Luis Miguel Ruiz -author of the four agreements, states that if you can be impeccable with your word, peace and joy will be yours for the rest of your days!
Think about it, if you can stay true to what you agreed upon with friends, family or foes- the need to give excuses or explanations wouldn't be needed! For example, if you say and give your word that you will follow through with something so personal and private, but you don't and instead betray their word, how do you think you will ever ever be trusted? At first, of course you may give one or two chances, but after three- should anyone ever ever trust you? Don't think so- but the person who betrayed your word may think that it's a joke or something juvenile to stick to your word!
Being true to your word is all you have! And if you don't stick to it, you will become a target! You will be perceived as weak and easy to take advantage of! You must hold fast and stick to your guns for if the person who betrayed you has no self respect, don't expect any for you!
