Being rich gives one a sense of "security" and for the most part, that's really why I wanna want more than i had while growing up. When I mean more, I mean millionaire more or maybe even billionaire... lol!
Yes, I also will want to be able to afford some of the cool stuff I see sometimes and "act like i didn't see", just because... And I would love to travel to so many places as well etc.... But all those come after security for me...
While flexing is fun and great, it just wouldn't work for me, so like you said, we all are different, with different views and personalities... I will love the rich "simple" life more, actually....
