Why do so many threads devolve into discussions about how many miles you have on your cars? Geez.
It's because the OP started this thread with how happy he was with his considered old car. So, other posters have to chime in to say theirs are even older, and that does not hamper their pursuit of happiness.
Having enjoyed a wide range of incomes over the years (from poverty level to top 1%), I can say from experience that more money has always made me happier...
Or rather, money should not make anything worse, unless one is an idiot and does not know how to manage it.
"I have never been in a situation where having money made it worse." - Clinton Jones
... While happiness might increase with more money, the stress of a high-paying job might affect happiness negatively by taking a toll on relationships, health, job satisfaction, etc... By retiring early, my wife and I have accepted a much lower income, which affects our happiness negatively, I have no doubt, but the lower stress level and greater freedom more than make up for it.
There is always some trade-off. If additional money comes with no hardship attached, who would say no? Or if one enjoyed the work that brings money, who would quit? I do not see any reason for Buffett to retire early, as long as his health holds out.
I enjoyed my work (it paid fairly well too) and would have continued if it weren't for megacorp's hassle. They could have upped the pay, and it would have been OK too. But they thought that I loved the work enough that they did not have to pay me more. They were wrong.
...And we still want more.
And that's a good thing, else we'd still be living in caves and crapping in the bushes.
Well, once we moved out from a cave and have a toilet and running water, why do we need to upgrade from a 1,500-sq.ft. to a 5,000-sq.ft. home?
There is some appeal to that in certain circles.
"I'd like to live as a poor man with lots of money." - Pablo Picasso
I am sure that Picasso still wanted good food and running water in the home. The point is that once basic needs are met, much else is really fluff.
... All it takes is one winter of scraping the ice off the windows and cleaning snow off in -35 to either build a garage or clean the one you have...
To keep on topic...having enough money to own a house with a garage ensures happiness for me.
Yes. But I maintain that it is still relative, because you see your neighbor driving his car out from his garage without having to scrape ice like you do. There are very few absolute things in life. We always measure our situation with that of surrounding people.
Great points ... On money ...
Now, What's the DDS synthesizer going to be used in ?
What will I have to do to you, once I tell you?
It is not important, other than that I have done a few PLL synthesizers, but not yet a low phase-noise DDS-PLL hybrid design. So, it's something I like to attempt now.
Not having to worry about money and having free time to pursue whatever interest one has on the spur of the moment is part of happiness.
