Another point about life: People who accept the rules of the "game" are not exactly happy. They just accepted it. Some use tricks like belief in another life. Have you ever stopped to think that this "promise" means exactly that life is inevitable suffering? Religion, for example, is always based on something that does not exist and there is no guarantee that it will exist in this life. Always after. Meanwhile, people who accept the rules go looking for happy moments amidst the chaos of random events. How many have you seen who, in "complete happiness", suddenly found themselves with some fatal disease? How many in accidents, etc.? Does it make any sense? None. But it does if we understand what living really means: fulfilling tasks in order to survive. Nothing more than that. We just had the bad luck of being aware of being alive. Other beings are like us, but without the burden of thinking about why they are moving, hunting, feeding, etc.
