I know a couple - and one in particular - who have done great for themselves in that situation.
I also realize there are hundreds of thousands that don't.
I feel sorry for some of them to a certain degree.
There's not a guy out there aged 25 who didn't make dopey decisions at 15 and I'd bet 99% of girls who get pregnant at 15 come to regret it massively as their life and maturity grows, but at that stage it's too late.
