Happiness is not always easy and sometimes it is a choice we have to make. Good news is that happy people tend to have better job prospects, earn more money, better health and have better relationships. Happiness needs to be worked on like any other habit. It takes regular practice for it to become easier. There are ways to improve your happiness level.:

Doing exercise daily is a great way to improve your mood, health and increase the endorpines in your system.
Create meaningful relationships. Professor Robert Waldinger, a psychiatrist explains “Good relationships don’t just protect our bodies; they also protects our brains”. Loneliness can be very damaging to our health and happiness.
Another study shows that meditation can be very helpful for mental health. It changes the way the brain reacts to stress and can increase the baseline level of happiness.
