"Life has its ups and downs" someone said, and I thought up and down is a state of mind: our minds make meanings of an unknown Destiny to decide how happy or unhappy we should be. And happiness is complex: we are happy about various situations to different degrees, while being unhappy about various situations to different degrees. And unhappiness doesn't necessarily mean 'down': Is there an experience of joyful-unhappiness?: when we decide to be unhappy about a situation while joyfully striving to improve the situation to increase our joy and happiness.
