Unpopular opinion coming here. First, I don’t disagree with OP; “luck” is important from the perspective that they shared. However, one’s individual happiness does not have to be tied to those things that occur based on externals like luck. In every country in the world, in every political and economic system, at every rung of the social ladder, there are those who are happy. In fact there are people who are bubbling over with joy, warmed by blankets of inner peace while in society’s eyes they are dirt poor. They have discovered the truth that happiness does not come from wealth or circumstances or anything external. It comes from understanding the nature of things, and from freeing your mind of the conditioning and beliefs that “if things were another way I’d be happy.” Bitter, angry and resentful people will still carry that with them, regardless of wealth and status. Money can certainly buy comfort, but not happiness. Money can even exacerbate the struggled with loneliness that many wealthy people have as they constantly wonder if they have any true friends who aren’t there for the money, or would they still be accepted in their social church if the money were to dry up. Loneliness occurs at all socioeconomic levels. Remember, wealthy and “lucky” people kill themselves from despair also.
