There are several reasons why we need to learn and apply gratitude. For one, it can help us be more appreciative of and satisfied with what we have, lessening our need and greed for insignificant things. In addition, it can help us feel more positive about the things that happen in life.
More importantly, gratitude has been linked to our mental, emotional, and physical health. People who practice gratitude are more able to control their state of mind and being. They feel less stressed and anxious, which leads to a calmer and more relaxing life.
