Wow, how do you manage to save 50%? That's very impressive regardless of your salary.
I would think that if you made enough, saving 50% would be easy. Maybe it's because I have no real desire to live the big life, with multiple fancy cars or big mansions. Even if I made a million a year, I think I would still live in a large "normal" house with maybe a cabin in the mountains. Big estates are just too much to deal with, and I wouldn't want that. And I have no interest in fancy cars. If I made even $200,000 a year, I think I would be saving a large percentage of that.
My current savings plan is to save enough to pay enough to get out of the house I'm in and into a nicer, slightly larger one.
