People undervalue $1 million (or similar numbers) incredibly. It doesn't mean you don't have to work, but it pays for just about all of the things you end up working the first 15 years of your life for - house, furniture, "stuff". Once you've purchased all that crap, any money you make over and above that actually seems like a lot more because it's not going toward buying couches and bedroom sets.

I made my first million when I was 22, and though it didn't keep me from working ever again, it basically paid for all of the things I needed. Anything beyond that has been incremental gains. It's a lifestyle changing amount of money.
