Happiness is a condition we create for ourselves regardless of external or internal conditions.
We have to decide to be happy. You can win gold at the Olympics and still feel miserable while another person may fail their exams and be joyful for having tried.
Happiness is not instinctively inherited. It’s a conscious way of life.
Make your days happy, whether or not things go according to plan, whether or not you’re rich or poor, whether or not you’re healthy or sick.
And see the quality of your life improve.
