Happiness. It is not easy to reach it and often we think that we are close to happiness. I’d start with the positive texts here. The Bible also teaches us to be positive. A recipe for happiness can be found here. Still, it’s not always easy to be happy.
I think happiness is to have people who loves you. Happiness is also when you do what you love, maybe some job.
Without courage, happiness is impossible. In my country people say happiness follow people who have courage.
