Continue living like a college student for 5 years after you leave college and you'll never need to worry about saving for retirement.
It really is that easy. You're going from a state where you have $500/month in expenses and zero income to a state where you have $5,000/month in income. It's trivial to save $10k/year at that point unless you go out of your way not to.
Even at 10% returns (which you can pretty much always get), your money will double every five years. Don't touch it 30 years, and that's a lot of doubling. And speaking of 30, that's when you can stop.
I essentially retired when I was 30 years old, and now just work the occasional short contract to pay the rent. Meanwhile the stack keeps growing in the background, waiting for grey-haired Jason to retire on it 20 years from now.
