I know how you feel. It's like a calling that you get. You're lucky that the calling hit you during your school years. I work at a university, and I can tell you that it's easier to get your education while you are in the mode. Once you get out in the workforce, it's difficult to make that comittment again. I've had a few students who have worked for me, that dropped out to make some quick money, and they almost never come back.
I posted a comment awhile back about my previous jobs and how I'm glad that I'm doing what I do now (University Web Coordinator). I'm glad that you made the decision to change directions in life. It's good to do that, and then most importantly "DON'T LOOK BACK!" If your happier doing Perl and working with computers, then who cares what you 'could' have been doing. I know that I appreciate your presence in the monestary. Most importantly, we wish you great future success!
