Learning to experience gratitude involves being grateful as an attitude, not as a reaction when good things occur. To be grateful, one does not need to wait until things are perfect. In fact, practicing gratitude makes one receptive to life's blessings, and these blessings continue as we continue to be thankful.

In one study, described by author Robert Emmons, participants who wrote about five things for which they were grateful experienced more positive emotional states and were more likely to help others over a period of ten weeks than were participants who wrote about the hassles and stressors they experienced during the same time.
