The big thing is that around 900k is when you get diminishing returns on savings vs market fluctuations. Bumping that amount by 10% would require saving $90k, which is a tall order. Or you could wait for a 10% market increase (it's up 14% this year). Not that the market is guaranteed to go up, or even by that much (we're in an unusually good market at the moment with inflated optimism). But at a certain point you hit a tradeoff where the market on average increases your wealth faster than savings off your salary will. At that point it makes sense to transition to a job that just covers your cost of living - one that you like more and offers more freedom.
