What is "being happy"? Does it even repay thought? One mostly just is, moment by moment, ups and downs. Though there may be particular things one hates (one's job of course cough cough - obviously) and more diffuse things sometimes, and one may have some overarching darkness. But if one is not clinically depressed at the moment or something (obviously deeply unhappy), how would one even know if one was "happy"? Moods come and go, right? One might hate one's job though
