This is so true. In fact, I'd wager that my perl skills are ultimately the most valuable component of my resume. I learned perl in 10th grade by hacking on AIM robots, messing around with the Net::AIM module I found on CPAN.
Then I got a job [still in 10th grade] writing a robot for some woman in Canada. This was fundamentally a huge thing, because it opened my eyes to the possibility that I, despite my lack of formal credentials, could generate income based on my skillset.
Honestly I haven't touched perl in years, and now most of my hacking is in PHP/JavaScript, and honestly I'm happy that I don't have to deal with perl anymore...but it definitely gives me some cred.
