2. Spend some time outside
If you would ask what can i do to be happy, another tip is to have a walk every single day. Just a half an hour a day spent outside is enough to increase your level of happiness. Combine a short walk with a short exercise in the morning or during a break. A simple walk at a park, in the street, in the backyard can make you feel more healthy and happy. If you make it a habit, you will see the difference if not immediately, then after some time for sure.
