I'm in my early 30s, married, living in California. For work, I do computer programming (AKA software "engineering"). On one hand, many would not complain about being paid quite good wages for what I do.
On the other hand, I find there are many ways it doesn't mesh with my values. I don't like the marketing / new-features driven nature of this industry, I like good craftsmanship (perhaps this is why I've recently gotten interested in hand-tool woodworking.) I really wish there was more time for gradual improvement of products, rather than learning the same hard lessons over and over as organizations throw out the old for the new and shiny. I find myself changing jobs every 3 years, usually because I've gotten bored of the particular problem domain, having become one of the resident experts. And ultimately, it seems that no job can let me explore enough of my wide interests to be worth spending 40+ hours a week at. Also I just find it plain tiring to work for other people and feign some sort of loyalty to the corporate entity. Furthermore, it sucks up a lot of the energy I'd have for being social with people I'd actually like to hang out with.
At the moment, I think I'd be comfortable living off about one-quarter of my gross salary (not counting some recent stock plan stuff that has done quite well.) Not very ERE

I'm probably about a third of the way toward accumulating enough assets to comfortably retire.
I and my wife would probably like to buy a house fairly soon, though we're not in a great hurry, thankfully. While I don't like how overpriced houses are in the US (in large part due to the subsidies), there are a number of reasons I'd like to own rather than renting too.
Rather than grind away at working for another 10-20 years, I'm starting to consider other possibilities. There are certain limits on how much I drop my cost of living without significant lifestyle revision, but I have been looking at ways of making money, not the least of which is trading stocks and options, something I've gradually been accumulating experience at.
