Agree. These are the people that are more self-content and happier in life. They could be stubborn in their own way (one may see it) but they live by their decision and they own up. I look up to these characters
Yesterday I watched the Channel 8 show "Pillow Talk" (haven't watched Channel 8 drama for many years and was pleasantly surprised the show is quite nice). Anyway, one of the characters - the old auntie - said something like that - things that I want to do, I do it willingly and happily, other people do not appreciate is other people's business, not my business so nothing to be unhappy about.
