If you can live you life on 42000 I'd be impressed. I assume you mean 4x what you need yearly for a good life, daily? That's more reasonable, but I think you'd still struggle at 42k a year these days.
Location, location, location. I'm living a great life, missing nothing, and my monthly expenses are below $1500 a month (excluding travels, including medical insurance). That's for a 2 person household in a 1600ft² 4BR rental house nearby a larger city (350k population).
Is this in the US? If so I'm impressed. I've lived on that much myself, but it was out of necessity and one decent sized emergency and I'm not sure what I'd have done.
