As the proverb goes, "before becoming anything, be a human", for becoming a human any person should have certain values and ethics. And these are the kind of things you actually need not work for it. U can just inculcate them. After hearing the word 'ethics' you may think it is something huge. But it is just inculcating small habits like respecting the elders, treating people eqaully and so on. And by doing all these things not only the other person is happy but also we will be happy from within..
