I have enough and I'm happy with that. I don't really have dreams, if I won the lottery, I can't imeadiately say what I'd change (although it would be a surprise, as I don't play).
I have a nice house in a fairly rough area but the people are "decent". I have a good job and have always lived well within my means, I don't want fancy cars, holidays or clothes so, apart from some spells of financial hardship when young, have always saved and never had money worries.
I have a few friends/acquaintances and an interest where I belong to a club so I have an active social life but not particularly close friends. No one I'm in touch with every day, but I'm happy with that.
I feel very lucky to have got my boys to teens without too much trauma and I'm still married to their dad, though I have financial independence. I know, eventually, I'd be "OK" without him should the worst happen
TBH, I think the biggest factor in my "contentment" is the security and self esteem given to me by my parents. I'm happy with my own company and don't feel the need to prove myself to anyone with showy possessions etc. It's also meant I've always felt secure in my relationship with DH and not overly dependent on him. He makes me happy but he's not responsible for my happiness.
