At 600k you could work a job that covers your expenses only while investing the money, and have ballpark 1.2M in a decade. Another decade could put you around 2.4M. Saving just 10k/year would massively inflate these numbers.

I encourage you to think in terms of percents. The Trinity Study says you'll need about 25x your expenses saved. If you can lower your expenses by 5k/year, you can not only invest that money, but your target also lowered by 125k. That double whammy allows diligent savers to do very well and retire on a much shorter timeline than those spending 95%+ of their paycheck.
