If you can save up $500,000, then you can withdraw approx 20k a year (plus inflation) for the rest of your life.
If you save up $250,000, then you withdraw 10k a yaer (plus inflation) for the rest of your life. If you only need to live on 15k a year, then you only need to generate 5k a year in income.
With investing, you don't actually need to save $250/$500. Some of that will be taken care of by compound interest.
A life free of work can be achieved easily by 40 for most people, or 30 if you really want and planned for it. Idk your age though, it obviously depends on that. But you have the choice of getting out, at least. Also look into types of jobs, like seasonal vs hourly vs salary. Some jobs are easier to work 20h a week in (nursing), work seasonally (tax accountant), or choose your own hours (freelancer).
You can do it! It's totally worth looking for a change.
Thats certainly a nice thought... but Im 32 and I only just started going to school last year and am on track to graduate with just an Associates by the end of this year.
I have a feeling Im going to have to work for a very, very long time.
