Your word is the strongest currency you possess. It can not be emphasized strongly enough. Your word is your bond and your ability to keep your promises, no matter who they are to, is make or break on every single occasion. This is where trust is either built or destroyed. It is a constant battle and is never truly over. In some cases, it can take years to build a strong foundation. Unfortunately, no matter how strong the foundation, it can be destroyed in a single moment.
It is the polite and respectful thing to do. Honor matters. You can see it and feel it when you are near someone that has it. Those are the type of people you want to be around. Those are the types of people that they want around them. Words are more powerful than people tend to give them credit for. At the end of the day, your word is the only currency you have that is based solely on your actions. You have complete power and control over them.
Never make a promise you can’t keep. I understand, as well as most reasonable people, emergencies come up. Life is full of the unexpected. The only constant thing in life is change. This is where the strength of that foundation is put to the test. In a relationship where there is a strong foundation of trust and kept promises, it takes more than an emergency to demolish the value of your word. Unexpected things happen, accidents occur, emergencies take precedent, whatever the case may be.
Having built enough trust, and demonstrating to people that you are a person of character and that your word is absolute, it is understandable that had that emergency or unforeseen circumstance not occurred, you would have followed through without question. It is important to constantly strengthen the currency that is your word by always following through, no matter the discomfort or inconvenience. The stronger the value of your word, the more understanding you receive when unexpected things happen.
