“If ingratitude be numbered among the serious sins, then gratitude takes its place among the noblest of virtues." -Thomas S Monson 

"Current case studies and research show that cultivating and practicing gratitude can reduce symptoms in cases of mild to moderate depression and anxiety. Practicing gratitude can also lead to increases in optimism, vitality, happiness, a sense of well-being, and a greater satisfaction with life. Grateful people tend to generate more positive memories, reminding them of the good in their lives. Those with higher levels of gratitude are viewed as more empathetic and supportive, more forgiving, and more likely to assist others. Grateful people also report feeling less envious and more generous with their possessions. They thus enjoy better quality relationships.

"Gratitude also helps in coping with adversity. Those who practice it in times of adversity are more likely to seek and find a 'silver lining' in their experiences. Finally, those who try to feel greater levels of gratitude report fewer physical complaints, more time spent in physical exercise, and better sleep duration and quality." -Vaughn E. Worthen, Ph.D
