3. Practice mindfulness

Sit down daily and think through five to ten things you are grateful for. The trick is that you need to picture it in your mind and sit with that feeling of gratitude in your body. Doing this every day will rewire your brain to be naturally more grateful, and you’ll start feeling happier after every session.

It only takes eight weeks of gratitude practice for people to start showing changed brain patterns that lead to greater empathy and happiness.
