Good for you! That's the way this is supposed to work - this business of growing up.
I got out of college when I was 22 and out of my mother's house three months later. THAT was a big day!
The funny thing is...I have a marketing degree but didn't actually need it for my job! My first job out of college needed a degree and I barely made 22 grand that year. I now make 3 times that and while having a degree certainly made my resume look better it wasn't a must.
