Our house isn't huge but a nice 4 bed detached in a (much too large) garden in a lovely quiet lane. DH and I met quite late in life and were financially sorted (both owned houses without a mortgage as that was doable back in the day) - so when we bought this we were able to pool our finances and not have to worry too much. I had a good career for 25 years but gave up when I had the children, and took a part time term time job on minimum wage just to keep my brain alive. I work 9 hours a week but for the stimulation rather than the money (although a bit of pocket money of my own is nice)
I know we are very lucky - and our 'luck' came from being born in a time when houses were affordable, and from working very hard when we were younger. I had a mortgage at 21, and worked evenings, weekends, overtime, and took in lodgers. I shopped around to get the cheapest food options (13p faggots from the butchers) and always did my own DIY etc. DH was similar.
I do feel for people nowadays who can do all those things and still never even get on the housing ladder. Plus rents are just not affordable. My DCs are teens - DD would love to leave home and have a single life but I just can't see how that can ever happen for her. At least we may be able to help a bit.
But to go back to your question - yes, we are very happy. But I think that is because I do still work. I also do my husband's books. He has a self employed business alongside his three day a week employment, which takes a lot of time and work, so he is always busy. He also has an elderly mother who needs a lot of help to keep her (also large) garden under control, and various jobs round her house.
As well as my job, I have a huge garden that could take up all my time 24/7 - it's a bit of a millstone tbh although I do love it (but wonder what we will do when we are getting old and can't strim/climb ladders/trim hedges etc). The house is a period cottage and needs constant redecorating. The children are teens and need constant taxis. Life is great - and we are never bored. But I'm constantly stressed about all the DIY and housework that I'm not doing, or the 2 hours an evening it takes to water the garden when I'm shattered. I do meet friends for coffee or lunch occasionally but it's not a regular thing, and I'm currently massively behind on the work for my job because I have been ignoring it since the holidays started. So that is on my mind!
We are comfortable but not rich, and don't have much income. So no gardeners/cleaners/decorators etc. Our holiday is five days staying with friends on the south coast.
All first world problems and I know we are very lucky. We are all very happy - but certainly not bored rich 'housewives of wherever'......
