Once your number as high as $5.6m, is that even plausibly within the scope of early retirement? I feel like a lot of the value of getting a specific number is getting spooked by it! And then facing some real choices. Is it really worth N years of my working life to [live in the most expensive city in America] / [buy a large home] / [pay for 4 years of expensive American universities]? And this isn't even touching on stuff tech people often want that OP doesn't (private schools / resort vacations / expensive winter sports).
