Gratitude means thankfulness, noticing simple pleasures, and acknowledging everything that you receive. It shifts your focus from what your life lacks to the abundance that is already present. Psychological research has shown the surprising life improvements gained from the practice of gratitude.
Two psychologists, Michael McCollough and Robert Emmons, conducted an experience on gratitude and its effect on well being. The results of the study indicated that daily gratitude exercises resulted in higher reported levels of enthusiasm, determination, optimism, and energy. In addition, those who practiced gratitude experienced less depression and stress, were more likely to help others, worked out problems more regularly, and made greater progress toward achieving personal goals.
Therefore, it's important to practice gratitude. Here are a few reminders.
A common method is to get yourself a cute little notebook and write down 3 - 5 things that you're grateful for at the end of each day. They can be small things, or bigger things.
You can also send a handwritten letter or make a phone call to a person for whom you are thankful, expressing the gratitude. It will surely brighten their day, and in turn, yours.
Besides, for some, it may be a good idea to express their gratitude in person. It doesn't need to be formal. Just a simple gesture of thanks is only needed to feel the benefits of this kind of gratitude.
Finally, there are certain times you can devote to gratitude. For example, at the beginning of your meals, or at bedtime, or when your parents get home from work. Committing to a specific time establishes a practice of gratitude.
Once you become accustomed to looking for things to be grateful for, you will find that you begin to appreciate simple pleasures, which can make a day and even change a life.
