A promise is a commitment made to do something in the future or to refrain from doing something, giving a person reason to rely on the word. When a promise is given, it creates an obligation and an expectation for someone that there will be follow through. Promises are important because they help build trust, shape relationships, and allow people to plan. Keeping promises strengthens reliability, while breaking them can damage trust and make others less likely to depend on future promises. [email protected]
