"Gratitude is a positive experience that comes from recognizing gifts or blessings and feeling thankful. It is also an attitude, a way of perceiving life, in which individuals are willing to acknowledge and receive the beneficial actions of others on their behalf. Gratitude is also a habit that can be cultivated, causing one to focus on the blessings of life."
Brother Worthen also points out that those who cultivate and practice gratitude feel less depressed or anxious, and more happiness, with a greater sense of well-being. They are also healthier, more forgiving, less envious, more generous, and more able to cope with adversity.
(Mar 2010 Ensign, "The Value of Experiencing and Expressing Gratitude")
See here and here and here for ideas we have shared in the past for cultivating and experiencing gratitude. It doesn't take a lot of effort, your plan may include quiet reflection or some activity or daily reminder to pause and count your blessings. You and your family can do something as simple as:
printing a page of leaves from the computer,
cutting them out,
and writing on the back of each leaf something you thankful for. After stringing a ribbon through each leaf,
hang them on a "tree".
How do you cultivate gratitude in your life?
