Research shows that practicing gratitude can improve mental health by 25%. When we focus on what we have rather than what we lack, our brain chemistry changes. Keeping a gratitude journal for just five minutes a day has been proven to increase long-term wellbeing. This isn't about ignoring life's difficulties, but about balancing our perspective. Studies at UC Berkeley found grateful people have stronger immune systems and lower blood pressure. The act of thankfulness creates a positive feedback loop - the more we notice good things, the more good things we seem to have to notice. Try writing three things you're grateful for each night before bed for two weeks and observe the difference.
