A 2010 study found that there are five key items that contribute to positive thinking, which, in turn, results in happiness:
(1) being grateful, (2) being optimistic, (3) practicing acts of kindness, (4) relishing in how lucky you are, and, (5) using your strengths. It’s in being aware of these aspects of your daily life that positive thoughts will flow, providing for better well-being and overall joy.
