With a gratitude journal, you can "write your way to happiness," said therapist Elizabeth Irias, LMFT. Each night, take a few minutes to write down something positive about the day, she said, even if it's small. "Did your favourite song come on the radio, or did you enjoy a quiet moment watching your kids play peacefully together?" Reflecting on the positive parts of your day right before bed can help you sleep better and experience less stress overall, she told POPSUGAR. This can also turn into a running list of positivity that you can refer back to when your life gets tough, said therapist Onnie Michalsky, LCPC, NCC, of Michalsky Counseling and Health Coaching.
