I would have to second that. It really applies to anything, but for most anyone here, the technology-related fields.
You can know more than 90% of the people that have gone to school, which I did goto school, so I know a handful of ppl here that fit that description. The thing is marketability.
If you want to learn coding, networking, etc. You can learn best on your own usually or with a small group of ppl (be it online or IRL). It is far cheaper that way. But if you want a good job w/ good pay, you will have to go through the motions to get a degree usually.
This isn't to demean college or degrees. Same thing with experience and certification. It is really best to have a solid foundation of all 3 (experience, education, and certification).
To make up for not going to college right away, I would suggest doing volunteer work in the related field for experience, and maybe getting a related certification if possible. There are tons of project sites to volunteer at, I recently found a few from volunteermatch.org
For my resume, I made sure that whenever I wasn't employed doing computer work, I volunteered somewhere so there isn't a void in my resume. Which happens alot with contract work. If your coding, join a sourceforge.net project and contribute. More info about why you should help an open source project is
here .
Also, get your resume out there on job boards and be sure you take the time to make a good resume. Really sell yourself. If you aren't good at that, find someone to help you out or atleast have some other people look it over.
