no comparison really
when i graduated and turned 18, i became a responsible adult, joined the US Marines, traveled the world, made some money, had "relationships" with a couple of dozen women, bought my first car (and my second), rented my first apartment, got married, started to college - all before i was 25.
before that, i was just a kid living with my mom and dad
just because your "whole life" has been what has up until now, it doesn't mean it will always be that way
