This is somewhat a hypothetical what would you do, the monies are real, the people and names have been changed to protect the innocent:)
You are 50 years old and an old lost aunt just tossed you $500,000, if want to think about it the other way of leaving the $500,000 that's fine as well.
You have been saving and investing you whole life, house was paid off in you r 40's, have a couple of kids, if the world hangs together you will be good to FIRE at 60 if not a few years before without the new $500,000 that just dropped in your lap.
Now the to the question at hand, do you keep on working so you can now leave you kids a much more sizable legacy or say screw it and pull plug at 50 and spend the new found dollars? To put it another way this extra dollars can buy you 10 years of freedom or you can pay it forward to your kids if you keep on working.
You were never planning on leaving your kids much of anything unless you become plant food much quicker than you may have wanted.
You have many other options in the middle like work part time etc., most likely what I would do but for discussion lets keep it at both ends of the scale as noted above.
What say you?
